Super comfortable, PLUS gives the girls a boost. I wear one everyday. I'm around 5' 2" inches, 135 - 140 lbs, size 6 - 8, bust 38 B. I ordered by the size guide - a large - perfect fit. The bathroom slit isn't well designed - too small - but it stretches out after a bit and you learn to use it for your own personal body structure. No problem so far with the heat in sultry June in the Southeast... well worth the investment. Love the way it turns my 50-year-old-sags into curves!
