I dont think they went really out of fashion, i've seen girls wearing them these days, and it just depends on how they look on you, if you like them and they fit you well why not wear them
I wouldnt wear them personally, but that is just because you know what they say about white jeans making you look fat, like Rosie said, so i avoid wearing white jeans lol
Those look nice on the person who is wearing them though, if that is you, they look great on you.
