If there are two pieces of fashion sense that my late Grandma left me, it’s this: Don't wear white after Labor Day. And warm colors are for fall while pastel colors bling best in spring.

Well, I sure was in for a surprise as I strolled through International Plaza this weekend.

No, I wasn’t suffering from sticker shock. Rather, it was the realization that designers this season have debunked those certain fashion truths I had always held to be self evident.

Amidst the usual holiday-inspired metallics, plaids, reds and blues, there was another color receiving top billing in store display windows: Mint green.

I have personally always associated mint green with things like blooming flowers and ice cream. My first thought was that the stores had completely jumped the gun and were promoting Easter before Christmas had even gotten here.

But from what I can tell, mint green was very popular on runways in spring 2012. And the color –- which designers are calling everything from seafoam to jade to confection green to (wait for it! wait for it!...) holiday -– is obviously hanging around for winter, popping up on garments specifically designed for cooler weather.

Case in point:

Wool Blend Sweater, Ann Taylor

Blazer, H&M

Cardigan, Wet Seal

Pants (with an accompanying shaggy mohair-like sweater), Ann Taylor

Sequined cardigan, Maurices

Woolen jacket, Urban Outfitters

And what outfit is complete without a few accessories?

Bracelet, Forever 21

Necklace, Ann Taylor

What do you all think? Does light green look out of place in winter? Should we throw away that old rule forbidding white while it's cold? What about the garments featured here: Fug or fab?
