But the design is so classic that it's super easy to find without resorting to dropping major cash for the Tom Ford original!

Avril Lavigne and Chad Kroeger were a color coordinated couple at the opening ceremony of the Huading Awards in Macau, China on Monday.
The newlyweds cleaned up nicely for the event in black-and-white ensems, with Chad in a black suit and tie and Avril in a Brian Rennie for Basler peplum gown.
Mrs. Kroeger's stripes are a little reminiscent of Beetlejuice, but we'll consider this an improvement from her last Halloween-esque outfit!
In fact, the 28-year-old looked very mature with her side-swept, curled mane and smoldering eyes! She even threw on some diamonds for the special occasion, including her massive wedding ring!
We think it's safe to say that this is the musical pair's best red carpet look to date!
They should totes get black-tie dressed all the time! LOLz!
