2 pairs leggings NWOT

I got these leggings thinking they would fit me with leggings I thought I might be able to fit a medium but they were too big the other ones I remember buying because they have a leather or biker Style to them even though they're not leather So I liked them but they were a little too big they don't have any tags on them I would have ordered a size small unless they were out so I consider those ones a small medium because either they were out so I got a medium or I did get a small and they just ran a tidbit big on me it's hard for me to tell because they are close to fitting and not as big as the other ones so other than trying when they haven't been worn or washed and both have a soft feel on the inside.
