I purchased this because I'm rather large in the chest and my swimsuit just wouldn't stay in the right place. This tape definitely worked and I had no issues with anything budging. The only downside for me is that I have sensitive skin and the tape does irritate my skin. No rashes or anything, but its sore and red for a day or two after.

Regardless, I've continued to use the tape for not only my swim suit but for dresses and tops as well since it works so well. Overall, I would recommend it.
