Whether you’re looking to fix a too-tight shirt or simply want a swingier silhouette, I’ve got a super easy tutorial showing how to add fabric to a shirt to make it bigger (find more 20+ ways to refashion clothes bigger here)! My shape definitely changed after two kids (see this post for more about how postpartum self care & sewing has intersected for me!) and I feel much more comfortable with looser tops. Instead of scouring the thrift store racks for a shirt with the right cut, I can pick up whatever suits my fancy and it takes half an hour to add a fun accent fabric instead.

This post was sponsored by JOANN, which means they supplied materials and compensated me for my time, but all opinions are my own.

JOANN just released new knit prints for fall and I immediately jumped on this fun leopard one. It’s a nice, medium weight knit without any see through issues and felt comparable to my original shirt so I knew it would mesh well.

So much comfier! It’s a fun way to add an accent of leopard or another fabric you might not want to wear in an entire garment too.

This is a very beginner friendly refashion tutorial, I took lots of pictures and spelled out every step. If you haven’t sewn much with knits, this is a great place to start!

How to add fabric to a shirt to make it bigger



Step 1- Cut up the side seam of your shirt! You can go all the way up to the armpit seam but I opted to end a little below that, just based off the shape I was going for.

Step 2- Lay out your insert fabric, making sure that the stretch direction matches up with your shirt. This will make sure that it hangs nicely! Lay it out flat and lay your shirt over top of it, pulling it as wide as you’d like. The wider the base, the swingier the shirt will be. The gap between my striped hems is approximately 6 inches wide. Use your marking pen to trace this opening.

Step 3- Time to draw our your hem allowance! You might want to consult your original tshirt to see if you want it to match; I was more concerned about ease of hemming. I used this fusible hem tape, so I laid it out and traced around, so that the finished edge would match up with the edge I traced out to match in between the striped sides. You could also measure if you prefer, I am more of an eyeball it person when it comes to refashions.

Step 4- Then it’s time to cut out the sides! You’ll want to add a seam allowance to each long side of the triangle you drew, extending past the top. I went for a 1/2″ seam allowance – so under the blue digital line was my marking pen line, and I measure 1/2″ past that, cutting it out along that line.

Step 5- Use the triangle you just cut out as a pattern, cutting a mirrored one of the same fabric, keeping in mind that the stretch is going the same way!

Step 6- Hem the bottom of both triangles, keeping in mind where you drew the hem allowance so it all matches up and you can line up stitching lines with the original shirt.

Step 7- Sew the insets in! Pin them right sides together and then stitch along the seam allowance line you originally drew. If you do not feel confident, try it with a basting (long as it’ll go) stitch so you can try it on and seam rip as needed. Once you’re sure it is how you’d like, I’d recommend using a stretch stitch like the triple stitch I used or a zig zag. Do one side, smooth.

and then sew the other side the same way!

Step 9- Use an iron to press the seams to the outside on both sides.

This is what the inside should look like.

Step 10- If you didn’t go all the way to the armpit seam like me, you’ll want to smooth out the seam allowance on the side. I put a white line just outside of where I actually stitched so it is easier to see; I went from the original armpit seam and gently went out at a diagonal until I met the stitching line from the inset.

You’re done! Try on your shirt and enjoy your roomier size!
