I'm "bigger" too. I find that Coquette has some really nice pieces that are comfortable and work well for larger frames. I like babydolls because they hide the belly well, but you're a little bit limited on having your arms covered. Perhaps purchasing a babydoll/robe set in a basic color would be a good idea since the robe could be worn with other items.

Dreamgirl runs small, so be careful of that. Some of the brands are true to size and some aren't. The great thing about Eden is that it's easy to return the items that don't fit! So it's okay to take chances! less
