I'm 15 weeks and not really showing yet but my current gym leggings are a bit tight and uncomfortable doing some exercises.... In fairness they do have a control top. Is it worth paying loads of money for maternity gym leggings or should I just get something cheaper but the next size up? Maternity clothes are so expensive and I can't tell if they'll last me right through the pregnancy. Anyone got any advice? I saw some at sweaty Betty that have a fold over top, but I wasn't sure cos they cost £65! If they're worth it I would totally make the investment though. Thoughts?
