Quick answer: The Sherwood Luna is a women's jacket-style BCD sold in sizes X-Small through Large and three colors: magenta, tiffany and phantom.
A women's cut can sit better through the chest and hips than a unisex BCD. To be straight with you, the Luna tops out at Large. If you need more room, look at the unisex BCDs in our collection that run to XX-Large and 3X-Large.
Measure your chest and waist over your exposure suit and compare against Sherwood's women's size chart.
