Dresses That Changed My Life: Gisele Bundchen in Versace at the Met Costume Gala, 2008

I'm going to go so far as to proclaim the picture of Gisele and Tom Brady at the Met's Costume Gala in 2008 as ICONIC.

Fresh scrubbed and fluffy!

These two look like champagne: light, crisp, refreshing and DELICIOUS!

But let's get to the point: Gisele's Versace dress.

This is a DTCML for the simple fact it touches on perfection in multiple ways. 

First: fit.  LIKE A GLOVE. 
Second: cut. Perfect.  Sexy without being smutty; revealing without being obscene.
Third: color and texture.  This light, delicate blush color would look good on essentially anyone.  That is no easy feat for a color, mind you.  The fact it is paired with a fabric so reflective and silky (and obviously of high quality, since it has a SHEEN, not a SHINE) takes it from lovely to GORGEOUS.
Fourth: detail.  The beading detail is absolutely astounding.  It is, essentially, a contradiction: it is simple and yet extremely intricate.  The fact it trails down the skirt of the dress to the floor without looking ridiculous is a testament to the cut as well as Gisele's physique.

Absolutely breathtaking.  Versace reached a pinnacle with this.
