Hi all, starting to plan my 33 pieces for January - March, and the priority is WARM and fits under snowpants and jacket!! Wondering if anyone has recommendations for leggings that are thick enough to be worn as actual clothing, as well as t's long enough to cover my bum in sed leggings. Budget-wise preferable! I think Aritzia might be a good spot to try, although more of a splurge? Anywhere else?

Thanks for any recos
