Wolford and Falke are both fantastic, but they're $70 a pop and I lose them all the time, god knows how.
More excitingly, coloured and patterned and textured tights are getting even more popular and available than they already were. I've been loving grey ribbed thigh-high socks all winter, and I got a great pair of cream, argyle-imprinted tights in a goodie bag from the Jaeha. Plus, Deborah Sweeney put a pair of hand-dyed brightly coloured acid-trip knee-stockings in hers.
On international runways there has also been a plethora of cute legwear, from traditional tartans at D & G by Dolce and Gabbana (I'm sure my Mum, and Princess Fergie had a few pairs of those in the 80s, to team with their Sloan Ranger-style hairbows and sensible navy jumpers).

The ubiquitous but nevertheless very covetable black lace tights continue to make many an appearance, seen here on Louise of Pandora Pandora.

Charlotte Ronson's recent catwalk show saw models donning sheer, under-the-knee black stockings.

And Eley Kishimoto's SS09 show featured all sorts of different stockings, as below.

My favourites, however, are the moody, grey and just-sheer-enough florals by Chloe, the perfect offset to a sweet floral or a simple black dress.
