When I chatted with Microsoft just prior to Windows 10's launch, they did mention that like Xbox One, the Xbox App will also get monthly updates.
A small t or casual shirt equates to a 36-inch chest. Casual shirts are small, medium, large, or extra large. A dress shirt is identified by the neck and sleeve measurements; a small having a 14-14 1/2 inch neck and 32/33 sleeve length unless you are especially tall, then it might be 34/35.
While there is no standard definition of a t-shirt, most people think of shirts that have short sleeves, no buttons, and no collar as a t-shirt. T-shirts offer casual comfort to wearers, but most t-shirts are only appropriate for warm weather. While long-sleeve t-shirts may not really fit into the definition, the shirts have become popular since the 1970s. They are comprised of the same material and generally same design as regular t-shirts, but they simply have elongated sleeves.
