yes I do polish my toe nails during winter, In winter i mostly polish with a clear polish with a white tip (french mani). I think it makes my toes look nice and feminine. I dont really do colors on my toes during winter as i found it comes off too easy when I wear boots and I love wearing boots, especially knee high boots with a nice heel.
In summer, i paint my toes in colors, as i wear mostly open shoes in summer. My fav colors, blue, green, red and maroon. I even wear a toe ring on one toes on each foot. The polish again makes my toes look feminine.
My hands, I almost always have nail polish on, the same fav colors as my toes or just a french mani.. sometimes even some nail art.
