I want to buy some matt black soft, stretchy, high waisted leggings that are as good quality as Swetty Betty. But not as expensive. By this I mean they keep their shape, v well made (strong seams), last 5 years of pretty solid wear, sweat wicking and not see through. Or to get all this do I just need to swallow the price? I don't want shiny black BTW, all the ones I saw in M and S for example were shiny/slippy which is not what I want.
