The T-shirt is a wardrobe must regardless of season. In the summer, it’s one and done. But in cooler months, it’s a styling tool that can underpin a range of looks.

And a gauzy V-neck paired with knits of varying textures is the ultimate in cozy chic. Here, we’ve found the best tees to rely on when you’re craving the essentials, from designer takes to $10 steals.
