Bought this top last year in Cacti and Black. Super supportive and holds up very well. Color has n't faded at all on either. Wearing it now for 2nd season. Impressive top. Paired it with the rushed mid- rise bottoms for a great suit.

I needed a supportive, easy to get on/off, and cute top for Aqua Fit. Even though I wear it under a rashguard it needed to be cute AND fit well, and it does. Comfortable as well. Highly recommend.

I love this bathing suit top for the feel, fit, and color.

5 12jess12
I recently purchased this and I ’ m pleasantly surprised. The material, fit, and coverage all exceed my expectations. I haven ’ t worn it in the water yet, so I can ’ t speak to how it holds up when swimming.

5 RoseR7
I 've been on the hunt for a two- piece swimsuit that's seamless, comfortable, and supportive enough to wear under a wetsuit, and I ’ ve finally found it! After trying numerous tops and multiple one- piece swimsuits, this two- piece stands out as the most comfortable by far. Plus, it ’s not just functional—it ’s also flattering and stylish, resembling a regular sports bra. Additionally, the material is high- quality, and buttery- soft. Compared to other tops that I ’ ve tried, the difference is the double- layer seams which eliminates any seams rubbing against your skin. After trying it on, I ’ m officially a fan of CALIA. It's also true to size- try it and you wo n't regret it.

5 julie26abc
Great coverage, doesn ’ t stretch out, and my favorite color- purple. I wear it every week& plan to pack it for my trip to Hawaii.

5 Avid Dicks Shopper
Fits great, and supportive! Love that it has a similar feel to a sports bra but just not as tight.
