Jordan's clothing item number is irregular, you can look at the size, men's S-170cm-175cm L-180cm XL-180cm XXL-185cm (there is another width here, I don't quite remember. L is as long as XL, but its width is different. )
It can also be distinguished from the tag: the tag of men is wider.
The women's tag is a little longer.
Actually, I can tell from my pants. Women's trousers in AD are all low-waisted, while men's trousers are looser.
