I haven't bought tights in years, having lived in jeans, but I want to smarten myself up a bit and start wearing dresses/skirts.
I'm going to Westfield Stratford later this week, so a vast number of shops to choose from including M&S and John Lewis. My trip isn't primarily for shopping though, so won't have a great deal of time to look.
I'm looking for opaques (probably 80 denier), and a good fit for 5'9" size 14-16 that hold their shape after a few wears and washes.
