I think these are adaptor suits what these lads are wearing (pic is big), they look alright to me, im far from being an expert of suits, though.
The thing with ready to wear suits though is that they stay the same (proportions stay the same, only the scale changes) even though everyone is different. You really do have to try them on and be ready to walk away. So many things to go wrong, generally length issues are fixable (within reason) but width issues are not. Then there are matters of pitch and balance...basically choose whatever suit sits smoothest on you yet doesn't cramp *any* of your movement.
