Hands down the best purchase of Fall/Winter 2012 for me was my Veronica Beard blazer. http://www.veronicabeard.com/collections/spring-2012
The knit “sweater” is really just a pair of knit cuffs and collar. It is so warm, and there is no winter bulk of an actual fisherman’s knit sweater underneath. Genius!
The spring line looks just as clever!

I am regretting not getting one at the trunk show at Gretta Luxe.
The hardest part of owning one of these blazers is then limiting yourself with the number of dickey sets you buy!
