So I measured Olivia and here is what her measurements were: Wasit: 20" Thighs: 13" Rise: 16" I measured the rise from just below her belly button, down around the crotch to around the same area on her back. Going by those measurements she should be in the extra large according to the pattern, but the large fits her much better. The rise measurement on the pattern is going to be much larger though to account for all of the stuffing. I may try to do another extra large for her, but make the waistband and cuffs the size of the large and see how that works. Let me know Allie's measurements and we'll see how she compares and then I will get one together for you. The sizing is definitely going to be the hardest part of getting something ready to sell. I may just have to post them really cheap to just cover materials and shipping and ask for feedback in return since I don't know a whole lot of kids this age with parents willing to even try cloth to test them for me!
