I love the Helen Jon Solstice Bra! As I've aged, I've found it more difficult to feel comfortable in a bikini top. I'm larger-busted and find that the wide band provides a lot of support, and the wide front straps and shape of the cups eliminates the 'side-spillage' that can be an issue for me. The periwinkle color is gorgeous, too!
I have this swimsuit in the blue and the orange flowers. They are the first 2 pieces I have bought in years, and have tried to find similar suits in other brands, to no avail.
The coverage on the butt is great-not completely over everything, but not showing everything, like you see know. The top is super flattering and fits just right. I am about a 34c, and a small was perfect, so maybe size a size down from your normal because every other brand, small is too small.
