Replying to Difference in womens and mens pants... (sizing)

I'll get right to the point, i am going to order some womens holden classics in a size small, i can fit into a mens small pretty easily but they are a little tight on the waist. I am assuming the girls pants will have a larger waist considering they need hip room to bear a child if you know what i mean... so if you could tell me if the pants would fit me or not that would be greeeeeeaaaaaaaaat thanks. Yeah yeah yeah i am 5'6 135.
