You're packing for the Jackson Hole Wine Auction and the first thing you put in your luggage is The Portland Collection Women's Sheep Springs Denim Vest. This reversible little number will work for both the Grand Wine Tasting and the private residence dinner you've purchased. Cotton takes the shape of denim on one side with two slash pockets for your phone and drink tickets. On the other side, 100% virgin wool sports a blanket-based pattern for a more colorful appearance. Skinny jeans, cowboy boots and this trim-fitting vest will have you blending in with the crowd at the wine tasting extravaganza.  Wear the Sheep Springs vest, a long leather skirt (or tailored leather pants), and a sleek silk blouse when going to someone's home for a meal prepared by a 4-star chef.
