I love soft sweaters, old tshirts, collared shirts, and even just white sheets to hide areas.
Stay away from corsets and things with boning. They are hard to pose in comfortably.
Unless it is the only thing you are wearing, I don't recommend a lot of jewelry. The focus of the photos need to be on YOU, not your sparkly necklace. I love stud earrings, simple bracelets and your wedding/engagement/this-ring-is-just-for-me rings!
I love jewel toned colors and neutrals. Steer clear of neons, bright colors and things with a lot of pattern.
Stockings, hose and thigh highs are great but not necessary. If you want to wear these with your outfit, please get them 2 sizes TOO big, as they fit perfectly when bigger.
Closed toed shoes are best and my favorites are nude or black pumps/stilettos with out straps at the ankle. Don't worry - you won't be walking much!
For lingerie I LOVE high waisted panties and body suits to hide tummies. They compliment every size and hide all the areas we don't like :) Some great places to find these are:
