Really love the Reefy socks. They're breathable, not too thick or thin, and stylish.
I love James Baldwin so this was a must have. Since it's a boxy fit, I wasn't sure about sizing. I'm normally a unisex M but I sized down to S because I didn't want it to look too wide on me. For size reference I'm 5'5 1/2, 165lbs, athletic build. I probably would've been ok with a M but I like how the S fits.
