The last time we saw a shift towards lingerie as outerwear was the 1980s, and while I exude a general disdain for that decade I can't help but admit that certain fashion elements which emerged from it do have a place in this decade and the next. And so it is that we see various pieces of underwear return to the fore as outwear to feature amongst 2009 and 2010 fashion trends. And in many ways this may become one of the ubiquitous fashion trends; one that is transseasonal, and one that emerges as we pay fresh attention to tights and stockings as a feature piece, and not just an accessory, courtesy of the ripped stockings trend.

But what elements exactly? And how do women play to the racy element without going so far as to look cheap?
I have a confession. I hate the 1980s.
Born in the middle of the decade I'm too young to remember any of its culture, instead preferring endless memories of Thomas The Tank Engine. That may be a lie actually, I do remember part of the culture. I remember perms. I remember mullets. I remember a plethora of crimes committed against my young eyes by baby boomers who should have known better (though that generation aren't exactly known for getting anything right). And amongst those heinous crimes which aided the development of my acute sense of loathing all things 80s is double denim.
Which brings me to some terrible news dear readers: double denim is back.

But there's hope. There's hope that we've caught it soon enough. There's hope that we can show people the error of their ways before double denim spreads. And Fashionising.com is going to lead the charge: normally fully behind the majority of fashion trends and micro-trends, we're labelling the double denim fashion trend the major faux pas amongst all of 2009's fashion trends and 2010's fashion trends.
As it did with bohemian inspired looks as one of the first 2009 fashion trends, fashion has gone global for Spring/Summer 2009, with designers drawing inspiration from every corner of the globe. A look which started with Yves Saint Laurent's legendary safari jump suits has been re-interpreted this season, and designers from Christopher Kane to Paul Smith have looked to Africa and the Orient for their muse.

Tribal themes can be seen with the strong use of animal prints at Christopher Kane, in cheetah and leopard print tops, combined with geometric shaped skirts in earthy hues such as grass green. Turbans also crop up again and again, another simple way to update your wardrobe for this season's fascination with global fashion.
Need a sexy dress update for your wardrobe this Spring? Look no further than bearing a flash of cheeky shoulder with a beautiful one-shoulder creation. Shoulders are sexy. More mysterious than cleavage and more elegant than legs; shoulders remind us of the delicacy and vulnerability of the neck.

Huge in 2008, one-shouldered pieces are again a major part of 2009's fashion trends.
The line between the office shoe and the fetish heel has become increasingly blurred; while the popularity of the ubiquitous Herve Leger bandage dress has simultaneously become widespread, meaning the super-short and super-tight is more commonplace than ever. The taboo, in many ways, is not so taboo anymore. Fashion has pushed the envelope and perusing the Spring/Summer 2009 runways, it's not hard to spot the bondage and fetish inspirations behind many of the clothes; making this yet another of 2009's fashion trends.

When it comes to 2009 fashion trends the sheer clothing trend may be the ultimate proof that throughout the year less will be more. But it's not the year's only trend doing just that.

It's a logical flow-on from the one-shoulder fashion trend; a new breed of draping Grecian Goddess dresses. A notable runway trend for 2009, anything with a Grecian or Romanesque inspiration is a sure hit for the Spring/Summer 2009 season.
