If it didn’t run large, I’d love this top. Unfortunately, following the size chart led me to a size that’s too large for me, so the underwire-lined, built-in bra cups don’t fit correctly or provide any support. I hope that one size smaller will fit! It took some finagling, but I was able to adjust the straps past a point where the straps get just thicker enough to not easily fit through the plastic adjustment pieces. With some patience, you can work the fabric through it though, without snapping the plastic pieces. I planned to wear it under see through dresses, with the matching shorts, but it’ll also work as a top if you’re younger or in better shape or just more confident than I am. The zipper in the back seems unnecessary, since the fabric is quite stretchy, soft, & sturdy. But, perhaps it helps if you have the correct size🤷🏻‍♀️.
