Hi Benita! The thing you're looking for is opaque tights...they're VERY popular despite all the pictures you're seeing. Make sure you check whether they have feet or not. (If you're wearing boots, it doesn't matter because you can wear socks with them and it won't show, but if you're wearing shoes, you definitely want them with feet.) Black is the most classic and versatile colour, especially if your shoes are black, but you could also go with other neutrals or even a fun colour like purple/maroon (can be very cheerful in winter). Some of the tights you can get are really warm -- look for merino or fleece-lined tights, they're like wearing long underwear or a sweater on your legs. Black opaque tights can be reasonably dressy (I wear them to the office) but for a fancy evening party or similar, I'd wear black semi-opaque nylons. In warm weather, no hose, just bare legs and dressy shoes. Hope that helps!
