Hi Marina,
So glad to hear you are loving the Sienna Tank.

My favorite!
I have this top and the matching Midori bottoms in 5 different colors. I’m 30 years old with a semi athletic build, 34C cup size. The large size in both tops and bottoms fit me perfectly! I love surfing and going to the beach in this suit all summer long. It’s supportive, flattering, sexy and keeps everything in place. Vitamin A is the only brand of bathing suits I own. Nothing else compares!
