As you can see there's only a 1.5" difference in sizing between sizes (there are a few exceptions in the very small or large where it's 3")
RL and many other makers use a 4" spread so you won't get a fit as with the Lacoste unless you just happen to match a certain size.S may be a 36", M a 40 and large a 44 etc
btw, your waist is 2" above the navel
Lacoste and PRL have few different cuts on their f/s shirts. Ok these are on their dress shirts not on their polo shirts.
PRL- classic, custom and slim (s,m,l,xl…)
Lacoste- classic, slim and lacoste live(super slim) – Sizing starts at (38,39,40…….)
Lacoste don’t use s,m or l on their dress shirts. ( or maybe just in Australian stocks)
PRL slim fit shirt (S size) is a little bit bigger than the lacoste live 38 and a little slimmer than lacoste slim fit 38 shirts.
But the shoulder is same on all the three shirts. I own many of them shirts form both brands and can upload picture to prove this.
Being 38 chest and 28 waist I cant wear PRL classic or custom or Lacoste classic shirts. So don’t know about fitting on them.
