Choose a large, baggy t-shirt that you want to modify. Turn it inside out, then cut the sleeves off right at the seams, so that the original seam is still attached to the body of the shirt.^{[1]XResearch source}
Flatten the sleeves first, then cut the entire seam off. Leave the hem on and set the sleeves aside.^{[2]XResearch source}

Choose a shirt that fits you, then set it on top of the bigger shirt. Turn the smaller shirt inside out first, then tuck the sleeves in so that they are out of the way. Set the smaller shirt down on top of the bigger one. Make sure that the collars and shoulders match up.
- Make sure that the front of both shirts is facing up.
- You can also use a fitted t-shirt or a sleeveless shirt for this.
4
Trace around the smaller shirt, adding seam allowances. You'll need to trace around the armholes and the sides of the smaller shirt. Be sure to add a ½ inch (1.27-centimeter) seam allowance.^{[3]XResearch source}
- It is best to use a dressmaker's pen (light colors) or a dressmaker's chalk (dark colors) for this. If you can't find one, use a washable pen.
- If the bigger shirt is too long, you'll need to trace 1 inch (2.54 centimeters) below the smaller shirt as well.
5
Pin the bigger shirt, then cut it. Set aside the smaller shirt, then pin the larger one, just inside the lines that you drew. Cut the shirt with sharp fabric scissors, following the lines that you drew. Remove the pins when you are done, but keep them handy for a later step.^{[4]XResearch source}
- The pins are there to keep the fabric from slipping around while cutting the shirt.
6
Pin and sew the sleeves onto the shirt. Open up the shirt and the sleeves. Pin the sleeves to the shoulders with the right sides facing in. Sew the sleeves to the shoulders using a matching thread color, a ½-inch (1.27-centimeter) seam allowance and a stretch stitch. Remove the pins as you sew.^{[5]XResearch source}
- Backstitch at the start and end of your sewing to make it stronger.
- Trim the sleeves down if they are too wide for the shirt.
7
Sew the side seams on the shirt and sleeves. Flatten the shirt so that the seams on the sleeves and sides match up. Sew it using a matching thread color, a ½-inch (1.27-centimeter) seam allowance, and a stretch stitch. Start sewing at the sleeve hem, and finish sewing at the bottom hem of the shirt.^{[6]XResearch source}
- Remember to backstitch at the start and end of your sewing.
- Use sewing pins to hold the shirt together, if needed, but remember to take them out as you sew.
8
Hem the sleeves and bottom if needed. Try the shirt on. If the sleeves or hem are too long, make a mark where you want them to end, then take the shirt off. Fold the sleeves/hem down at the mark. Sew using a matching thread color, ½-inch (½7-centimeter) seam allowance, and a stretch stitch. Trim off the excess hem, if needed, as close to the stitching as you can.^{[7]XResearch source}
- Remember to backstitch at the start and end of your sewing!
- For a more realistic shirt, add a second line of stitching just below the first one.
- Begin and finish sewing at a seam, not the middle of the hem. This will help disguise the backstitching.
After this, your new shirt is ready to wear! You don't need to serge the seams on the inside of the shirt because the material does not fray. You can, however, trim the seams down to make them narrower.

Making a Tight T-Shirt Looser

This method only works for shirts that are too tight, and within reason. The shirt still needs to fit you reasonably well at the shoulders. While it is possible to make a small shirt bigger, there is only so much you can do.
Flatten the shirt first, then cut the seams off, starting at the bottom hem and finishing at the sleeve. You want to cut the side hems on the sleeves off as well, but leave the sleeves attached to the shirt.^{[8]XResearch source}
3
Find a suitable material for the side panels. You will be using this material to fill in the gaps on the sides of the shirt as well as on the underside of the sleeves. Use a matching jersey material, preferably from a matching shirt; if you can't find any, you can buy some from the fabric store.^{[9]XResearch source}
- Having trouble finding the exact color? Consider a contrasting color! If the shirt has a print on it, match the color to that.
4
Cut the material into a tapering rectangle to fill in the gap. Use a measuring tape to measure from the edge of the sleeve to the armpit of the shirt, then down to the hem. Cut two rectangles based on that measurement. Plan on making the rectangles 6 inches (15.24 centimeters) on the bottom and 5 inches (12.7 centimeters) at the top.^{[10]XResearch source}
- If you cut the material from another shirt, make the bottom hem the 6-inch (15.24-centimeter) wide edge. Add 1-inch (2.54 centimeters) to the overall length for hem allowances.
- If you cut the material from store-bought fabric, add 2 inches (5.08 centimeters) to the overall length for hem allowances.
- You can cut the panels wider/narrower to suit your needs.
5
Pin the panels to the shirt. Turn the panels and the shirt so that the wrong sides are facing out. Pin the front and back left side edges of the shirt to the side edges of your first panel. Make sure that you are pinning the cut edges of the sleeve to the panel as well. Repeat this step for the right side and second panel.^{[11]XResearch source}
- If you cut the panels from an existing shirt, make sure that the bottom hems match up.
- If you cut the panels from store-bought fabric, leave an even amount of panel sticking out of the sleeve and bottom hems.
6
Sew the panels to the shirt. Start sewing at the bottom hem and finish sewing at the edge of the sleeve. Use a ½-inch (1.27-centimeter) seam allowance, a stretch stitch, and a matching thread color. Remove the pins as you sew.^{[12]XResearch source}
- Backstitch at the start and end of your sewing. This will make the seams stronger.
7
Hem the panels. Fold the edges down on the top and bottom of each panel until they match up with the existing hems on the sleeves and shirt. Pin them in place, then sew them down. You will need to adjust your seam allowances to match those on the existing hems. In most cases, you'll need to sew two rows of stitching. Remove the pins when you are done, then trim off the excess material, as close to the stitching as you can.
- Backstitch at the start and end of your sewing.
- If you cut the material from an existing shirt, you'll only need to do the hem on the sleeve.
8
Add the final touches, then turn the shirt right-side-out. Go over the shirt, and snip off any excess, hanging threads. If you want to, you can cut the collar of the shirt off as well. You can leave the collar raw for a trendy look, of you can hem it.^{[13]XResearch source}
- You don't need to finish the inside seams, but you can trim them down to make them narrower.

Turning a Crew Neck into a V-Neck

Download Article

You only need to remove the collar from the front of the shirt. When you reach the shoulders, stop; leave the back of the collar intact.^{[14]XResearch source}
Find the middle of the collar, then cut it. You will end up with two straps on either side of the shirt.^{[15]XResearch source}
Use the straps from the original collar as a guide so that you don't cut the V too deep. It's okay if you stretch the straps a little, but not too much. The V needs to start at the left edge of the collar, and finish at the right.^{[16]XResearch source}
4
Pin the left side of the collar down first. Make sure that you are pinning the collar face-down, with the folded edge facing downward, and the raw edge facing up. You will eventually turn the collar up to hide the seam.^{[17]XResearch source}
- Pull the collar enough so that it extends to the right side of the collar by ¼ to ½ inch (0.64 to 1.27-centimeters).
5
Fold the end of the collar until it lines up with the bottom of the V. Depending on how much you extended it by, this will be between ¼ and ½ inch (0.64 and 1.27 centimeters). Secure the fold with a pin, if needed.^{[18]XResearch source}
- Folding the end of the collar will create a neat seam on the front.
6
Sew the collar down. Begin sewing at the shoulder and finish sewing at the bottom of the V; adjust the folded end, if needed. Use a ¼-inch (0.64-centimeter) seam allowance, a matching thread color, and a stretch stitch.^{[19]XResearch source}
- Backstitch at the start and end of your sewing for extra strength.
- Remove the pins as you sew.
7
Pin and sew the right side of the collar. Pin the right side of the collar, making sure to overlap the left side. Sew it using a ¼-inch (0.64-centimeter) seam allowance, a matching thread color, and a stretch stitch. Remove the pins when you are done.^{[20]XResearch source}
- There is no need to fold down the end of the collar for this side.
- Remember to backstitch at the start and end of your sewing.
Use a needle and a matching thread color for this. Make sure that you sew through both layers on the right collar, and only one layer on the left collar. This way, you won't see the stitching on the front.^{[21]XResearch source}
Fold the collar up so that it sits naturally, like a regular shirt collar. Tuck the hem down so that it is pressed against the shirt material. Iron the collar using the cotton setting on your iron.

1
Cut the collar off to make it a scoop neck. Trace around the front collar, adding 2 inches (5.08 centimeters) on the sides and 1 inch (2.54 centimeters) to the bottom. Flip the shirt over, and trace along the back collar, adding 1 inch (2.54 centimeters) all around. Cut along the lines that you drew.^{[22]XResearch source}
- You can leave the edges raw, or hem them for a neater finish.
2
Create a side-tied shirt. Cut the side seams off of a t-shirt, from bottom hem to armpit. Cut 2-inch (5.08-centimeter) slits into the sides of the shirt, 1 to 2 inches (2.54 to 5.08 centimeters) apart. Tug on the tassels to stretch them. Tie each front tassel to the matching back tassel in a tight, double-knot.^{[23]XResearch source}
- Cut through both the front and back layers of the shirt at the same time so that the slits are even.
- Cut the collar off to make it a scoop neck if desired.
3
Extend a short t-shirt with lace. Cut enough lace to wrap around the hem of your shirt, plus an added 4 inches (10.16 centimeters), then cut the lace in half. Tuck each piece of lace into the shirt by ½ inch (1.27-centimeters). Pin one piece to the front hem and the other piece to the back hem; overlap the side edges by 1 inch (2.54 centimeters). Sew the lace down, following the original stitching on the shirt.
- Backstitch at the start and end of your sewing for added strength.
- Use gathered lace, or gather it yourself, for a more feminine touch.^{[24]XResearch source}
- You can use a similar method to add lace to sleeves. You'll need just one piece of lace for each sleeve, however.^{[25]XResearch source}
4
Tie dye a shirt for a burst of color. Wash the shirt first, but don't dry it. Bundle it up, then wrap rubber bands around it. Mix up a batch of fabric, then apply it to the shirt using a plastic squeeze bottle. Leave the shirt in a plastic, zippered bag for several hours. Rinse the shirt with cold water, then undo the ties and rinse it with warm water.^{[26]XResearch source}
- Skip the bundling and rubber bands, and dip-dye the shirt for an ombre look.
5
Stencil a shirt with fabric paint. Tuck a piece of cardboard inside your shirt. Place a stencil on top and secure it with tape, if needed. Apply fabric paint using a sponge brush; work your way from the edges of the stencil inward. Let the paint dry, then peel the stencil away.^{[27]XResearch source}
- For a trendier look, use fabric spray paint instead.
- For something more unique, use bleach spray.^{[28]XResearch source}
- Create your own stencils using freezer paper.
6
Try an iron-on transfer. Purchase a pre-made iron-on transfer design, or print your own using a printer and blank iron-on transfer paper. Cut the design out, place it face-down on your shirt, and iron it following the instructions on the package. Peel the transfer paper away, then wear the shirt!
- If you are printing out your own design, remember to reverse it first!
- Follow the directions on the iron-on packet very clearly and make sure that your shirt is pre-washed to prevent the print from coming off.
- Hold and press the iron on the iron-on transfer and apply constant heat to the iron-on transfer.

Question
Is there a way to pull up (ruche) both sides of the tee shirt to give the bottom hem a draped look?
Community Answer
Turn the shirt inside out, then sew down both of the side seams using a straight stitch. Pull on the thread to gather it, then knot it off. Turn the shirt right-side-out when you are done.
