I've noticed that I'm the only one in yoga class wearing Primark leggings. Everyone else has these hippy imprint yoga pants but when I look them up online they all seem to cost £90! Are there any really good companies that make proper stretchy leggings that don't slide or gape or ride up but don't cost so much? I'm overweight so would prefer something not too lairy in colour. Dark greys and navys are ideal.
