They have always been common. Men's/women's shoes/clothes/accessories/fashions, etc.
Student or Learner
Structures like "men's" and "women's" have become more common until recently. Are they correct? Would you please clarify the usage for me? Thank you
Shouldn't we say " mens' or womens' clothes" instead of men's and women's?
No, 'men' and 'women' are already plural.
We put the apostrophe after the plural form with an s.
Eg. My mother's car = my parent's car (one parent); My mother's and father's car = my parents' car (two parents).
But with "men's" and "women's" you can't make them any more plural than they already are.
"The man's car" becomes "The men's cars" not "The mens' cars". If the plural of 'man' was 'mans', it would be "the mans' cars".
