denim hotpants, dip-dye hair and onesies-- the fashion fads of 2012 that simply have to go

FASHION fades, but style is eternal.

With the January sales in full swing, we asked Ireland's most style savvy celebs what 2012 fashion fads should be ditched.

Top of the Ditch-It list was the celebs' favourite: the fleecy, oh-so cosy onesie.

Rihanna, One Direction, Louis Walsh, Robbie Williams may all be fans, but Off The Rails presenter Brendan Courtney is definitely not impressed.

"Hate them," he exclaims. "They are everywhere, all the models love them. They've got to go. They are just awful."

British retail chain Asda stocked one million onesies in the run-up to Christmas, but according to Brendan they are on the way out. "They can't stay around. They are just too ridiculous."

Dublin stylist Helen Egan (32) agrees wholeheartedly.

"Onesies should be burnt. All of them. It's a moment of madness that has gone global."

Print on print was huge this year and fashion magazines encouraged us to clash whenever and wherever possible.

"Clashing prints were all over the catwalk. Miu Miu went mad for them," Brendan says. "It's very kooky but it's also a very hard look to pull off.

"I know what people are going for, but all too often you end up looking like a demented granny."

Peplum was de rigueur for many women this festive season. The flirty look was a godsend, hiding a multitude of sins after all those mince pies and turkey dinners. But Helen says it's too much of a good thing.

"I'm over peplum. It's on everything. You can practically get peplum trousers."

From Caroline Flack to Gisele, the 'dip-dye' hair -- or balayage, as many of us will know it -- was this year's 'Rachel' do. Everyone wanted the laid-back Australian beach blonde look. But celebrity hair stylist Dylan Bradshaw says that badly done balayage has killed it for him.

"I've seen so many terrible versions. It's a very hard technique to get right. I think we all need a bit of a break from balayage."

Over the past year, more and more teenage girls have been throwing on high-waisted denim shorts and fishnet tights. Helen thinks this look needs to go, and fast.

"There's a real fad for fishnets and hot pants combo," she says. "That's a real no-no. I'm tired of seeing girls with hot pants half way up their arse."

Shiny high-waisted leggings with crop tops were another fashion faux pas.

"Super skinny leggings are a hard look to pull off," Helen says. "I think a lot of girls are trying to channel their inner Sandy from Grease, but unless you have the physique of a model, don't do it.

"Loads of girls teamed the leggings with those tiny crop tops. There was just too much skin on show."

Brendan Courtney and Sonya Lennon have just released their own style book Your Best You and say that keeping things understated is the way forward.
