I would have to try on the item in a store first to get the exact size before I would buy clothing online Garde Meubles Marseille.  (like Jeans or slacks)
The only exception would be t-shirts but they are less critical than dress shirts.

When the only size measurement is S-M-L-XL it's pretty easy figure out what to wear.

Yes, but it's like working twice. The best would be to determine your size and compare the price after.
