Happy Tanabata! (Sorry for the scenery.)
No, I didn't make the kimono; got it on eBay It is actually a Dress Me Hello Kitty item. It's a bit tight at the bottom and a bit loose at the top, but not bad overall. The bow just has Velcro on the back, but I'll sew it to elastic at some point. Shellie May was just too excited to share even though she's technically several days early for the actual Star Festival, I think? I'm going to try on the other two I bought later and see how those fit.
(My local mall had an adorable sailor outfit in the Dress Me Hello Kitty line on clearance for about $15, I think...I'm almost certain it would fit Shellie May but I didn't try it...I'm hoping the price goes down more. )
