I'm very pale (and ginger/freckly) and I've been slightly furious to discover that a tan covers up so many sins! Spots, scarring, random bruises, veins - it makes me look slimmer, it makes my eyes stand out more, makes my teeth look whiter.
And when I say 'a tan' I mean, I'm so pale that a standard fake tan actually just brings me to a more normal skin colour. I did a top up of my existing fake tan the other week for the first time ever (I've only actually fake tanned about 6 times) and had a panic that I was orange - looked at pictures from the day where I'm in amongst crowds and I'm still one of the paler ones.
I'm annoyed that I feel better with a tan, tbh - I want to feel beautiful in my own pale skin, but I would look at photos of me and just get upset, I couldn't understand why I just looked a bit odd all the time, I would never have said it was my skin - it's only since trying tan this year and seeing photos of me and going 'oh... I look alright actually!' That it's clicked.
I see some people who really suit it, but despite being a redhead I think I'm just a touch TOO pale naturally, I don't think it suits me. But then I have been indoctrinated by years of seeing normal/tan skin. The only proper pale skin you see is in 50s style, burlesque style - and that's just not how I want to dress.
