This look is from Chicos and I love it for how to wear white jeans in winter. Gray and white is beautiful and on-trend this season. The long sweater and the knee-high boots over the jeans are very in-style right now, too. And I think you could change this up, too, substituting brown for the gray elements. I don't have gray suede knee-high boots and don't plan on buying any, but I do have brown, so I'll work it that way.
