I'm truly surprised at the jeans-as-wardrobe-staple, although likely I shouldn't be.
Um, hrm. Staples for winter during the day during the week is a black knitted skirt that falls just above the knee, a collection of turtlenecks in an assortment of colours, black tights, and over-sized men's cardigans to wear over top. Add black pumps with a reasonable heel for every-day wear indoors. Weekends is all about comfy. Camisole covered by a zippered hoodie, yoga pants/soccer pants/some kind of straight legged, loose fitting, comfortable wear.
That's the basics, I guess. Switch out black slacks for the skirt, also throw in an assortment of knitted dresses, scarves, and brightly coloured tights for variety.
That's winter stuff.
