I wear a size 33 waist in women's for jeans what would be my men's jean size be?

Jeans are jeans. Men and women are built differently.

If your waist is 33, the same will be true for a men's or women's jean pants. The problem will rise in your hip measurement. Men's jeans tend to be cur straight from the waist; women's pants taper outward from the hip.

The size you wear will depend on your personal build.
