Wear nude-for-you hosiery to achieve the appearance of bare legs, but with coverage and insulation. Opaque hosiery is thick and robust. Sheer hosiery is soft, delicate and pretty. Make a statement with patterned, lace, or non-neutral hosiery.
Sizing up in hosiery reduces the stretch, preventing pattern distortion and distributing the colour more evenly. A larger size can also be easier to pull on and off, and feels comfortable on the midsection. But not too large, or it will sag at the ankles.
If hosiery is not for you, wear leggings or long johns for warmth with skirts and dresses. Hosiery, leggings and long johns can all be worn discreetly by covering up with longer hemlines and taller boots. Or forego them entirely and stick to pants and jeans.
