I'm currently wearing black treggings from New Look - I like them to wear with knee boots, especially because they're thicker fabric than leggings so I can get away with them at work, but they're bobbling terribly and I've only worn them a few times. Where could I get a really decent pair? We don't have any shops here to speak of (except M+S, Peacocks and the aforementioned New Look) so I can't go out and feel a few pairs for myself! I need some recs so I can go on a tregging hunt at half-term.
