I'm not sure what is going on with the sizing of Boathouse apparel. But our team recently ordered a bunch of custom bras in the sizes they typically order, and what arrived fit about 2 sizes too small. (Boathouse is correcting the issue). That said, I was a little leery of ordering a unisuit especially when the interactive size guide came back saying that my 5'9" 135lb frame would require a Large. That made me wonder what size a typical 6' female rower would be ordering! I did order a large... and a medium. The medium was the better fit (good length but a little too big in the top half, which is my typical issue). High quality and arrived quickly. Return process for the unwanted Large uni was easy.
