I usually wear a size 10 in pants and I bought these pants that are a mixture of polyester & cotton. Someone I know, told me that polyester pants run "small", will these pants still fit?

Update:
I ordered these pants online, NOT in a actual store.

Update 2:
I'll just have to find out. If they don't fit, I'll return them

seems like you have it figured out, good luck pants man

reroll the properties on them if they dont fit, sometimes you can get some more flexible material that way

cotton pants usually run "big" so if you're lucky they'll be a perfect fit
