So cute! Top is wire - no strap (I am not missing it, it was not made to have one) nevertheless it shockingly does stay up!! Bottoms run really small in my opinion so medium is more like a small. (who actually wears the same size top and bottom right??) Go classy and wear navy or have fun and rock tropical floral, OR mix it up and mismatch. So cute! This was worn once and washed - it is perfect in everyway, you would never know it was worn.
