Find an online store with a good return policy and order a few things for her to try. If she's self-conscious, and wants your opinion, this will be a more comfy environment than having to skulk out of a changing room to show you. Personally I wouldn't go into crazy specifics about why you chose the clothes, what "works" with her body type, just say something basic like you could "picture" her in these outfits and they can all be returned if she doesn't like anything. No pressure. This might sound like walking on eggshells to a lot of people, but if you're happy with your relationship and this is a sensitive issue for her it could be a good way to introduce her to some different looks.
