I normally have to size up in swimwear due to a long torso. I picked Andie because of the long torso option. I was thinking of ordering a small long. But the website asked my weight and height and age and said most people would go for Medium. Anyway, medium long was much too big. I returned it and asked for advice. Based on my measurements Andie said my torso wasn't long and to order a small. But my instinct was to order small long as I always struggle with swimsuit length. In the end, I couldn't decide and didn't want to pay for a second return (the process was easy but they do charge you). So even though I loved the look and feel of it, uncertainty about sizing meant I didnt re-order.
