This dress is awesome! I didn't know it was going to really be in two parts but I think I like that better. I got the custom size so it fits perfect. Just one suggestion, I put 18 inches and it's maybe 3 inches above my knees without the petticoat, so if you want a longer skirt (maybe to the knee) go for 21 or 22 inches. (Also you might want to get a petticoat separately there is a "under skirt" that comes with it that is very puffy but I got one just in case. Hope this helps!
