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.
In the survey, white men ages 18 to 25 had, on average, a 41-inch chest, 35-inch waist, 41-inch hips and a 16-inch collar (that is raw neck size -- shirts are generally sized at least a half-inch bigger).
