Packing forces me to think about my wardrobe in a streamlined manner. There are a few essentials I always take without hesitation – one being a slim knit black turtleneck. I know it will be a workhorse worn under other knits when it’s cold or on its own as a classic piece that always looks chic. Slim is key for easy layering under jackets. Plus it’s a silhouette that can be dressed up for dinners. A black turtleneck is not a piece I’ll splurge on. I’ll save those dollars for pieces worthy of investing on. My focus is on comfort and fit and I prefer a flat knit over a rib. It’s more flattering to tuck in. Vince, COS, Theory usually fit the bill. A couple of seasons ago, Zara had a slightly cropped style (similar) in a very lightweight fabric. I bought it in black and gray and wore both so much on a trip to Vienna, I came home and bought two more for backup.
