Clothes here come in either Chinese sizes, which are quite small, or occasionally in western sizes.
In an effort to put off doing the laundry for couple of days I went shopping for t-shirts (plus at 4 for a dollar, it would be cheaper to wear them once and throw them away). I’m western size XXL, which equates to a 5XL in Chinese, which some tourist places do actually sell, hence why I’m now the proud owner of an assortment of classy ‘I Climbed The Great Wall’ t-shirts.
Noticed in the tourist shop that sizes go through the usual XS, S, M, L, XL for the Chinese, then 3XL and 5XL for the tourists, then the next size t-shirt up is simply labelled ‘VAST’ and the next size short is delicately labelled ‘LARD-ASS’ with a picture of a westerner in a cowboy hat.
