Designers Dan and Dean Caten already dress celebrities -- including outfitting Britney Spears for many a tour date -- in their body-conscious looks and now the design duo is making the most necessary celebrity accessory: sunglasses.

At last night's launch event in a far west Chelsea warehouse in NYC, the designers were all smiles in trim tuxedo blazers.

"It's more straightforward and not too blingy, and it's also a bit masculine-y, so it can be unisex," Dean told StyleList of the new line.

While the design duo weren't inspired by any particular celebrity, they still had the famed hills in mind. "It's old Hollywood meets new Hollywood!" Dan added.

And the celebrities turned out in droves. Rachel Zoe confessed that Fashion Week was "fashionably exhausting" but still made it out for the red carpet.

Of the runway shows she's seen, the celebrity stylist/reality TV star loved Marc Jacobs, Derek Lam and on designers Kate and Laura Mulleavy, Zoe adds, "Rodarte almost made me cry it was so amazing."

Wearing head-to-toe DSquared, but accessorizing with a Goyard clutch, Hilary Duff sang the duo's praises. "DSquared is one of my favorite lines. I've always had a huge respect for designers for their vision and creativity. Maybe I'll get to be there someday. My line [with DKNY] is more for everyday, but it was still a little nerve-wracking."

Inside the two-story warehouse space there were models aplenty, including Tyson Beckford, making the rounds in the line's new shades.

But the roof was where it was at. With a view that included the Empire State Building, guests whiled the night away drinking champers and dancing to the live DJ. Only two more days to go for New York Fashion Week!

We're glad to see the label being so practical -- after all, sunglasses are one accessory that's good for you!

The shape of your face is the most important factor when choosing any frames. The list below will give you some idea as to which fashion frames will suit your face shape.

Square face: Oval frames are best for a square face as they soften the jaw line. Avoid thin, angular styles and those with colour emphasis on the bottom rim

Round face: Angular or geometric styles are best for a round face. They draw attention to the top half of your face

Long face: A long face with high cheekbones requires wide frames with a strong top line. Avoid small, square frames - opt for a style with all over colour

Oval face: An oval face looks great in most styles! Be adventurous and try modern geometric shapes, which are stylish and fashionable

Heart-shaped face: A heart-shaped face can wear slender, rounded or square styles without decorative detail on the temples. Avoid styles which are wider at the top, these will reflect the face shape rather than balance it

This week we bring you the best of this season's Christmas clobber. We're thinking homemade-looking, 'Don't be so ungrateful darling! Granny spent six days knitting that' jumpers and cardigans.'

To kick things off we've found the most brilliant sheep jumper of all time. Now you too can own your very own piece of Wales for the grand sum of £29.50, courtesy of Ty Hanleigh Knitwear. Google it, we dare you!

For men, there's John Smedley's Rudolph Raoul jumper, which costs £167 (some of that goes to Children in Need, giving you a warm and fuzzy glow as you wave goodbye to your cash) and is knitted out of ultra-fine merino wool.

We've stumbled across a really gorgeous (and unbelievably cheap) reindeer jumper/dress for £15.99 from a website called CuteJapaneseFashion.com.

For the confident male shopper, we've picked out Urban Outfitter's lambswool cable-knit jumper (£140) by Acne Jeans. We suggest going all out and buying it in fuchsia pink. There are also some really hideous tight-fit jumpers made out of what seems to be recycled 90s skiwear, which we think are probably really fashionable but just can't bring ourselves to recommend. If you want to take a look, do it off your own back!

Finally, another men's option is this contrasting knit cardigan from Nanny State. It has cute toggle fastenings and a chunky collar to keep you warm (£84.99).

The RGB Glasses from designer Luís Porém are hollow and made to be filled with the ink colour of your choice. Want black glasses? Add black ink! Want pink glasses? Add pink ink! Want tortoiseshell glasses? Add brown, orange, and black ink! Want to frighten everyone you pass? Add the blood of your fallen enemies and smile while you gnaw on a raw arm.
