There a different ways to handle this and some are better than others. The vast majority of players dress their female characters in feminine clothing and male characters in masculine clothing. Not gender neutral stuff or cross dressing. A solution that ignores this is a bad solution.

School outfits (masc/fem for both) > maid and butler (masc and fem) > alphinaud outfit and hair (unisex for both) >>>>>>>> 2B outfit (fem for both and no masc option)

Of course the school outfit is the ideal way to handle it but they aren't going to do that for all glamours. That leads to less wearable options. The bunny set looks like crap on males and we got that instead of a nice Chippendale bunny set. The wedding dress doesn't bother me because there is a male suit as well. See where I'm going with this?
