I bought a few of these a year or so ago and I love them. I waited for a good sale and scooped up five more including the teal which is a great color. The first ones I bought I think I got small as that is what the size chart said. When I reordered I got medium because I just can’t believe I am a small? There is not that much difference and having both sizes addresses and weight variation. These are not structured old school bras very forgiving if a little small or a little big. I am 5’6 with medium build 155lbs.
