While I don't mind them overall, these are definitely not the same as Aligns. This one has a similar cut to the Aligns (including the inner seam and all) and they have the same smooth feel and fit. But they run a bit large so the fit was a bit off for me. I am a 4 in Lulus and got an S and it's a bit big even though the tag says US 4/6. It's still ok to wear to yoga but slips down a little. I'd get the XS for a more snug fit. What I liked least of all is the shiny material... kind of similar to sports tights from UnderArmour but not as good quality. I was expecting a softer, non-shiny material. I got the black ones so not sure if it's the case for all colours. Ok for the price but I'd only buy again if the material is different.
