Replying to Armada Arlington Vest Sizing

Sooo I'm 1.65m (~5'5"), wearing pretty baggy as in XXL pants, what size should I get L or XL (I know XXL Armada is too big).

Or more precise:
You guys know how long L and XL are for comparsion, and how baggy the vest is round the waist?

thx yo, k+ for answers
