Just a guess.
Other things.
Maybe.
And why do skinny jeans always be have to be 'prised from cold dead hands'?
I'm not being a dick, but when the question 'what does one wear in winter if not skinny jeans?' Comes up again.
The answer is: Anything. Yes, I get that the skinny jeans lovers all came of age in the late 90s when ridoncolous jeans were ubiquitous.
It's not binary wide jeans bad/skinny jeans good.
All jeans are good.
If you like jeans.
