Review on Women's Lightweight Full Zip Running Track Jacket - Stretchy Athletic Workout Jacket by Lawrence Allison

Love it! This is exactly the sexy, tight and breathable blazer I was looking for. This is a great underlayer perfect for outdoor running etc. It's breathable and lightweight so I wouldn't recommend it in the very cold months unless you're using it as a layer. However, I am very glad that I have a medium. I usually wear small shirts but the medium size was almost too small for me. If you're between S/M or slightly busty/baggy, I highly recommend going up to medium or even large for a more comfortable fit.
