Bests & Worsts Reviews from Amazon

I bought this and Leonisa to compare the two. I work from home in front of a computer all day so I needed something to help with my posture. This one runs a little small I'm normally a 38 d but after reading the reviews I decided to go for a 40 and it was perfect size. The fabric was nice to the touch and felt good on my skin. After 2 hours of wearing it I noticed that it wasn't holding up.it felt like a regular sports bra. I was slouching like normal. The Leonisa one I couldn't slouch it was uncomfortable. Compared to the Leonisa I could not tell that it was helping my posture or giving me back support. Even though the Leonisa is more expensive I would have to go with them for support.
