This is a boring one, but, given what British 'summers' are like I find 3/4 leggings useful to wear under dresses when it's not quite warm enough for bare legs. But having suprising difficulty finding just casual ones online, most seem to be sportswear styles.
I'd also like to have them in colours other than black/white/navy/grey - I know you can get every colour under the sun on amazon or ebay but I'd rather get good quality, ideally ethically sourced ones, rather than buying cheapo rubbish, looking to pay up to £30 or so.
I looked at Snag but they only have full length ones, M&S only seems to have plain colours or sports styles - any suggestions where I can find a good selection of what I'm after.
