A foodservice venue prohibits men wearing nothing but a pair of spotted boxer shorts, and perhaps a tank top (commonly called undershirts) or T-shirt, on the basis that it “is underwear” (what makes it underwear if it is not being worn underneath anything else)? 3 minutes later a woman wearing bright coloured, sleet and tight fitting yoga shorts without anything underneath them is allowed entry because the brightly coloured fabric of the yoga shorts suggests that it is intended to be worn as an outer garment.
A health club prohibits a man from entering the mixed sex sauna in boxers on the basis that it is not “proper swimwear” (and so “may make others uncomfortable), but women are allowed to enter wearing spaghetti strap thong-kinis that are much more provocative and revealing, because they are apparently made to be used as “proper swimwear”.
Is this indirect or otherwise sex discrimination, or is it otherwise unlawful?
