I have just duplicated a layering piece that has quickly become a workhorse in my wardrobe: Wink Knits and Layers Women's Long Sleeve Mock Neck Silky Tee.
Used to be the queen of Uniqlo Heat Tech, but what they call a "crew neck" is actually quite a significant scoop neck, while they only make a high neck in their Ultra Warm fabrication - too bulky for the kind of slim layer I was after.
So Wonder Wink it is! A wardrobe basic that makes many other items work in these cold months.
