I've mentioned that Myra has requested a Rapunzel costume for Halloween, and Simplicity was kind enough to provide an excellent pattern, but the last Simplicity/Disney Princess pattern I made for Myra had some major fit issues, so I knew I'd need a muslin. Have you ever tried to get a 3 year old to sit still long enough for a fitting? I don't recommend it. Myra is a sucker for a new dress however.
Simplicity 2065, the licensed Disney Tangled costume pattern. Since this was a trial garment, I didn't go to all the trouble of lining it, skipped the overskirt and the long lower sleeves. I used some remnant cotton coordinates from Hobby Lobby, so I shortened the skirt based on what my fabric would allow. I ended up having to add the bottom ruffle to make it a wearable length, but I think it's cute.
