Glam Girl S* wrote asking for help finding a bathing suit that would hide her tummy troubles and still leave her looking glamorous. I just went through this with my girlfriend Jen, who had a beautiful baby the day after Valentine's Day. We hunted high and low for a suit that would cinch everything in, but wouldn't make her look like a grandma in Boca. These were the two winners, both from Macy's. The second one is a tad less forgiving than the first, so pick depending on how much bulge needs to be disguised :)

I just read a fantastic post on Liberty London Girl's blog about the travails of finding the perfect swimsuit if you're busty. She's found her perfect suit, custom made!
