Championwomens Fleece Open Bottom Pant Sweatpants (pack of 1)

I need the old fashioned sweatpants that are smooth knit on the outside but have the soft knit inside. Are these like that?

I bought these before Chriastmas. They will cost me $14. more to buy now. Why?

My waist is 32 and hip is 42, i am not sure what size should i get? Any idea? Thanks

I just oredered these pants. Are they very thin?
