lip gloss is not stylish but its a decent strength if obvious man bait

I noticed a couple of women wearing lipgloss today. otherwise they were plainly dressed. it just makes me wonder why wear lip gloss. revealing fashion, like nylons and skirts, for example, could be just to look stylish, and well dressed. but lip gloss, not lipstick, is serves no purpose but to say: I'm on the market, take me now.
