I order a ladies small and it fit great, but wanted it a little more loose fit. So, I sent an email asking about the return process to exchange it for a medium. I immediately got a response to put it in the mail with the label provided and BAM!! My new shirt was at my house a few days later. Shirt is very light weight, perfect for the boat or beach.
Sizing: I’m about 5’4, 130lbs, 32dd. Small worked, but I preferred medium.
