Versatile Top
Bought in white EcoTex. I like how the the bottom of cups can be adjusted. It gives me options how much coverage I want. The textured pattern and gold tips on strings add a little luxury feel to it.

Hi There,
Thank you for leaving a review. So nice to hear how well the top fits. We love the texture of the suit as well. A very comfortable material.

Like but don't love
I prefer the weight of the non-EcoLux fabric for the Gia top. The edges with the EcoLux are a bit thick. But it is still very nice and I kept it. If they offered white in the other smooth fabric I would have exchanged it.
