I've got a big family birthday party to go to in July. I'll be 7 months pregnant and I'm looking for a casual/dressy dress to wear. Something between mid to knee length preferably.

It'll likely be at a restaurant or banquet hall.

Any suggestions on where to look besides Gaps, ON, H&M? I've heard OK things about asos Maternity.

Also hoping to spend no more than $30! LOL If I can't find something in that price range I'll just wear a regular (dressier) maxi I have in my closet. I'm not opposed to used if you've got one to sell between the sizes of 2-4 or XS/S!
