- Multi-Size Upcycled T-Shirt Romper and Dress Pattern
1. Cut the side seams of your tee to open it up. Fold the front in half along the center front.
2. Lay the pattern with the fold on the fold and the neckline lining up with the neckline. *The neckline might be a slightly different shape, but line it up the best you can.
3. Do the same with the back to cut out a back piece.
4. Cut out one gusset. Make sure the stretch is going the right way.
5. Lay the sleeves on top of each other. Line up the bottom of the sleeve pattern with the hem of the sleeves. Cut out two sleeves.
6. Cut out three facings. I layered my layers together so I only had to cut it out once.
The pieces you need: one front, one back, two sleeves, one gusset, and three facings.
1. Overlap the back neckline over the front neckline by 2.5". Pin and sew with a zigzag stitch along the edge.
2. Line up the sleeves with right sides together with the armscye. Pin and sew with a zigzag stitch with 1/4" seam allowance. Finish the edges with a zigzag or serger.
3. With right sides together line up the sleeves and edges of the romper with 1/4" seam allowance. Zigzag or serge the edges.
4. Take one of the facings. Line up the inside curve with the front inseam. With right sides together sew with 1/4" seam allowance.
5. Finish the outer curve of the front inseam.
6. Flip the facing around into the inside of the romper. Sew with a straight stitch .75" from the edge to tack the facing to the inside.
7. With right sides together line up the gusset with the back inseam curve. The gusset will fit right into the extra seam allowance on the back. The curve of the gusset is opposite to the curve of the inseam so it's a little tricky to sew. Sew with a zigzag at 1/4" seam allowance.
8. Take the last two facings. With right sides together sew around the outer curve with a zigzag stitch with a 1/4" seam allowance.
9. Turn right side out.
10. With right sides together line up the inside curve of the facing with the back inseam going around the gusset. Sew with a zigzag stitch at 1/4" seam allowance.
11. Serge or zigzag the edges.
12. Sew the seam allowance of the facing up towards the body of the romper with a straight stitch.
13. Fold up the legs 1/2" (including the front and back facings) and sew with a zigzag.
14. Add snaps or buttons to the faced inseams.
