No, the dress code should not be stricter on guys than girls. 1. Girls have more privates. Their chest should not be shown, while it's ok for a guy to show his pecs. 2. Styles are more exposing for girls. Popular styles for girls are short shorts (Mainly the Nike running ones), low-cut tops, and other skin-exposing outfits. The most exposing outfit a guy will normally ever where would be knee-length shorts and a T-shirt; not inappropriate in the slightest.
