II have no idea what baby doll cut means, but 'm with you on the no elastic front - and I'm not sure the size of your hips is the cause of the annoying behavior of jerseys with elastic. I have small hips, and the elastic drives me crazy too.
The jerseys I've been the happiest with are from Shebeest - but you still have to be careful since even some of their jerseys have elastic in the bottom. Their Bellisima jerseys and their Timeout jerseys don't have elastic in the bottoms, and I'm hoping that their SB sleeveless jersey is good too, since I just ordered one (along with a Bellisima short-sleeved jersey), both from Team Estrogen since I'm too lazy to drive to a bike shop!
Here's a link to the cycling jerseys page on the Shebeest web page - there are others there with descriptions that sound like elastic-free bottoms.
