This might seem odd, as stockings are typically associated with women. However, in French, "collants" refers to a garment that covers the legs from the waist to the feet, regardless of gender.
Here are some examples:
* Des collants pour femmes: Stockings for women.
* Des collants pour hommes: Stockings for men.
* Je porte des collants noirs aujourd'hui: I am wearing black stockings today.
