Aubrey V-Neck One-Piece Swimsuit

I’m 5’2, 122 lb, 32B, and usually a size 2 or 26 on bottom - athletic shaped. I ordered a size 2 & 4 to try on. First, it is a pretty swim suit that is high quality but the black one that I received looks like the blue one that is pictured - missing the side strings. The size 2 fits me on top, but the leg opening is cut too high and too cheeky for what I wanted (family beach vacay with small kiddos). The 4 is slightly better on the bottom but I see how it may not stay on as well on top once I’m moving about, so I would be too self conscious that it may slip down. I also have wide shoulders and this style adds more to the width. Overall, not for my body shape or what I want for an active beach vacation with small kiddos.
