Landsend has the Slendersuit tankini but you might have to play around with sizing.

Lands' End has these.

I've recently lost a good amount of weight - and still going - but most everything on my body still feels jiggly.

I'm looking for supportive tankini tops with a good deal of compression to help me feel more secure this summer. Ideally, I'd love something like those shaping bra camis (from Honeylove, etc.), except beach ready. Any recommendations?
