I've bought some Levi's stretch jeans (1pc elastane) that seemed great - and I couldn't even get into the size down in the shop. But they've immediately lost their tightness and feel a size too big now - I wouldn't recommend these as a brand. But so I can keep wearing them, has anyone ever managed to shrink down stretch jeans? I have read that you can't put elastane on a high heat - but as I want to shrink them down does it really matter. Thanks for any insights!
