These are the pants I wore in the fall and winter! They don't have a lining, but the fabric is thick, so I think they're perfect for this time of year m(__)m Regarding the size, they run a little large, so they should fit perfectly for those who usually wear a size M. For reference, the inseam is 68cm. The waist is elastic. If you have any other questions, please ask in the comments section m(__)m D
