If you are the accessories editor of In-Style or Vogue, or the handbag buyer for Browns or Net-a-Porter, you will, I concede, be instantly able to identify every "It" bag on the planet - from an Anya Hindmarch to a Zagliani, and everything in between.
If, way back in February, on reading that "fetish" was a key trend for autumn/winter 2011, you decided this was a trend too far, your reaction, I suspect, was similar to most of womankind. Most of us would have rolled our eyes, dismissed "fetish" as a gimmick and turned our minds to more vital matters, like how fit Gary Barlow is looking these days.
If you have a profound craving to update your wardrobe but an equally profound desire not to splurge, this is your moment. Because this season's trend for piling on statement accessories means that even the most cautious/recession-hit of us can look totally on-trend with a relatively minimal outlay.
Let's assume for a moment that, like me, you have peered under the lid of the dressing up box that bears the label "Autumn Winter 2011 trends", stuffed, as it is, with 1950s, 60s and 70s retro looks, with lashings of fetish and cross-dressing gear thrown in.
At what point did shoes move from being merely an accessory - albeit a crucial one in making your clothes work or not work - to being a style statement on the same elevated level as an It bag (and approaching similar price levels).
Hats are properly back on the fashion agenda this autumn for the first time since the 1980s. Back then, it was all about Princess Diana and the gorgeous, big-brimmed numbers by Graham Smith, John Boyd, Frederick Fox, Philip Somerville, et al, while for autumn it is all about wearable hats that also tick the season's huge retro trend.
In about a decade, when the High Street - and even Bond Street and Sloane Street - exist merely as showrooms to try on clothing that we will then go home and buy on the internet, the non-virtual fashion businesses which will remain will be the ones like Rous Iland.
