I'm sure this ones probably been put in here, but fake tan.
I fucking despise fake tan. I don't know if it's /that/ common in places like the States but in my euro-fag land, it's not uncommon for a lot of younger girls [think like, 15-16 year olds] or generally speaking women, especially around my age [so, in their 20's or older] to just fucking coat themselves in fake tan. It was a thing even back when I was a teenager lol.
I only consider it a trend because it's so common amongst younger women or mid to later teen girls and has been for years. It looks so gaudy, it's just terrible.
It's even more gross when you see older women doing it, on top of bad plastic surgery and obvious fillers, botox, etc. It's just... Gross. It doesn't look good on anyone. Literally not a soul looks fashionable making themselves look like a fuggin Oompa-Loompa.
Nothing wrong with anyone wanting to be a little fashionable or nice looking, even "older" women, but dear God, you do not need fake tan. It's just so awful.
