fleece-lined tights from Berkshire on Amazon for $14 look super perfect! There's even a 'tall' on the size chart. I have long legs. So while I don't need these specific ones, they sure do sound right.
I used to have lots of leggings from LuLaRoe. A pair of their one-size dark brown leggings would be fine, but I don't (ever) feel like paging through a consultant's page to see what they have. Shopping isn't usually a hobby for me, as much as a necessity from time to time.
The dresses are both blue-ish, with some brown in their prints. I don't like wearing black tights with them, but usually do anyway. I also don't have black boots, so I'd like to have tights/leggings that will match the boots I currently have for now. So dark brown it is.
