Just got this today and have used it once. I'm currently around a 38D for reference.  Definitely worth the money. I like that it zips in the front so I don't have to fasten it and twist it around or anything like that. Its staying up as a strapless, but comes with straps if you want to use them. My only issue is that I need to figure out a better way to get the suction funnel things in and out easier. The bra does a great job holding them in, I'm pretty sure it's just me needing to figure out how to work it.
