I don't think it's equivalent. Handing out T-shirts that are clearly labeled "unisex" suggests you are trying to accomodate both men and women. Maybe you could accuse someone of ignorance about how unisex T-shirts fit women (I never knew unisex didn't fit women), but I wouldn't accuse them of sexism, quite the opposite because they clearly intended to accomodate.
