My husband just under 180cm 75kg size at the suit fits well in L. The build quality is ok. and the fabric is pleasantly thin, so you do not break a sweat with mild underwear and dancing. Because of the hairy surface and the smell we have the costume first aired out ... well it is functioning properly; The monkey head is a bit small, but nicely decorated ... the value for money you have probably by the gorilla suit from Aldi more ;-)
