I don't mind popular fashions but I usually take a while to warm up to them. I didn't get my first pair of skinny jeans until about 2 years after they came into fashion. Now my number of various coloured jeans are my wardrobe staples. On my upper body it's t-shirts, cami's and tanks. I always try to wear a baggy sort of top with skinnies and if I have loose pants I will wear a tighter fitting top. I always have hard trouble finding dresses that look very good so I don't have many of those. It's the opposite for long maxi-dresses though, I can wear them very easily (no bra needed, just undies), and they're flattering on me as they cover all of my legs.
I used to pretty much wear my thongs all the time except for winter, but I got a nice pair of ballet flats for xmas and I've been wearing them too.
You'll seldom catch me with bare legs at work. It's long black slacks all year, even in summer, with my compulsory uniform shirt and either Docs or pixie boots.
