Okay, our first "Why Buy" is Levi's jeans leggings/ jeggings, whatever.
Why buy them?
Well. I've been wearing a pair for a year, and these were the "jeggings" that convinced me jeggings were, in fact, okay. They're less legging, more thin, exTREMELY skinny black jeans. They look good with absolutely ANYTHING you'd wear skinny black jeans with (for me, that's mostly everything but like... a bathing suit), and after wash after wash they haven't faded, nor do they look too annoyingly new.
While mine don't feel like they've shrunk, they do fit a little snug, so I'd probably size up. And I'd probably buy two pairs. Thank me laters.
