The phrase of this type:
Welcome to Amsterdam. When it's hot please dress for the body you have, not for the body you want. Thanks.
This phrase is taken from here:
In this context, it is not clear expression: "dress for the body you have, not for the body you want."
I am very interested to learn English language and culture and thus I'm curious to know how native English speakers understand this phrase.
I support the Russian language and can not translate this expression. Help me understand.
