Bests & Worsts Reviews from Amazon

Ordered an XL, I'm a women's size 14 40DD chest. This fit exactly how I wanted it to. It is tight and seems to run small but I feel like that makes the reason behind this vest even more effective. The material is thick enough to create heat, leading to increased sweat, but not bulky like a sauna suit. So you can wear this under tanks, sweatshirts and shirts! I began sweating while taking these photos! Had to take it off and hop in the shower lol If you'd like this to fit most comfortably, I would use the size chart to find the suggested size to order, then go up one size from there! The upper vest hugs my chest extremely tight but I feel secure! Actually, in the photos I'm not wearing a bra and don't plan to when I run in this. From the run and motion test I did around my house while wearing this, the bounce in my chest is decreased and I'm held securely whether it's completely zipped or not. The lower vest has enough coverage to cover my entire midsection. As you lose inches, you'll be able to adjust the waist wrap because of the Velcro. The velcro is strong!! UPDATE: I purchased another vest in the size 4XL. It fits my chest much better. Although I do like the extra security of the size XL I first purchased because it hold everything in tight. I'm more comfortable in the 4XL. I still don't have to wear a bra in the 4XL but there is more bouncy in my chest when I run than with the XL.
