If I have a size 30 waist should I get a small or medium?
It depends on how tall you are. If you're under 5'8, go small. if you're 5'8-5'10, medium.
You should get a small. If you want them slightly looser fitting, get a medium but keep in mind the waist will be huge so you'll definitely need a belt.
