So I'm going to be a bridesmaid in my BIL's wedding in August. If baby comes on his due date-ish I'll be 2 and a half months post partum. Of course it's time to order the dress I'll be wearing NOW though, and I'm at a loss for what will be the most flattering on my new mommy body. I'm figuring I'll order 2 sizes up from my normal pre-pregnancy size, but was wondering what you ladies who've been through it think about the cuts and styles of my top two choices. Things I'm considering:

It could be hot!
Nursing breaks
Insecurities about waist line

Anything else? Which dress would you choose for 2.5 mos PP?
