Hi Victoria,
Thanks for the review 💛

Flattering and comfortable
I really love this style of top. It’s flattering and looks refined. I don’t like tops that have a push up effect and this looks great to lounge by the pool.
It’s not super supportive, so don’t select this cut if you want something for activity. I ended up getting two styles
I’m a 32DD, 5’6” 132 lbs, selected 8/M

Hi Devon,
We appreciate your feedback! ☀️
Runs Really Small
I really wanted this suit to fit but they were so small! I normally wear a size medium. The Vitamin A tool recommended a size large so I sized up following their recommendation and they were still too small. The straps were far to short to allow the band to wrap around my chest. This size large fit like a small.
