A shirt- I used a size small for Brighton's black and gray dress, the one in this tute is an XL
and stuff for embellishments
9. Turn your shirt (now, dress body) inside out and place a sleeve in the arm hole, right sides together, lining up the seams in the arm pit.
10. Pin in place. You can see the top straight edge of the sleeve will NOT be pinned into the dress body. It will become part of the neckline.
14. Figure out how big to leave the neckline by trying it on your little one. Or just guess if they're a big stinker and you don't want to wrestle with them and your dress full of pins. Sew the ends of the elastic together and sew your casing closed. Now you have a cute neckline to your dress!
16. Pin your fabric together, but be sure not to get all the layers together. We're going to create a casing for the waist.
18. Turn your dress right side out, and find your waist band opening.
19. Thread some elastic through. Have your little one try it on again or just guess how big to leave the waist, sew the ends of the elastic together, and sew your casing closed (on the inside of the dress).
PS- I picked up a bunch of shirts on clearance at Walmart- The black and gray shirt was $3 and this gray and pink one was $1. Hurry! They were out of the black and gray when I went back this past weekend.
*Edit 8/13/2012: Just saw that this was getting pinned onto Pinterest so I wanted to put in here that Brighton is almost 5 and wearing this dress now. It fits her pretty perfect and she's mostly average in height and weight. You could always get two shirts if they're super cheap and add a ruffle on the bottom if you're making it for a girl who's taller or older. Enjoy!
