Hey, im aboutt 5'6 and male withh a fairly small frame but also fairly muscular, and I usually wear tighter fitting polo shirts and I bought a 5 (Medium) in a Lacoste polo and it was insanely big on me, I wear a M in A&F shirts (i guess I could wear a S but ehh.. it'd probly be a little TOO slim fitting), and I wear an S in AE polos. So I'm wondering how exactly do Lacoste Polos fit? Should I buy a 2 or a 3 because I'm really not sure but I love the material that Lacoste polos are made of and they seem to keep their color for quite some time.

so the 3 in lacoste fits like the S in A&F?
