Gonna make this one kind of quick! I made this costume in about 4 days for Wizard World Minneapolis, but it's probably going to come to Anime Central as well. Unfortunately my phone was having issues so the only way I could take photos was with SnapChat, so the quality is sub-par.
The skirt was a basic bubble skirt from a tutorial I spotted on Pinterest. Unfortunately it's a bit shorter than I would have liked, but it worked out. Basically the top/ bottom are gathered, and sewn to a lining that's 4" shorter than the gathered outside section.
The blouse was made from a free Burda Pattern, modified to have the correct ruffles, a standing collar, and long sleeves. This was SUPER fun to make and I love how it turned out! I'm currently working on a similar one for my Lolita Eren :)
The tights started as yellow stretch knit (a bit too yellow) and the dots were painted on. I used the Kwik Sew catsuit pattern, but I need to make them a bit tighter before the next wear.
The waist bow was simply 2 pieces of fabric, the "belt" section and the "bow" section, and they close together with pins. It's stitched to the front of the skirt to keep it in place.
Definitely the easiest costume I've ever made XD
