Ordered one because I was needing some long-sleeve running tees.  This one arrived and I wore it the next day.  LOVE THIS!  My street-clothes are an 8/10 and I usually order a Medium, as I did here.  Roomy enough that I can layer, which is what I needed for our midwestern winter runs.  Nice long sleeves, comfortable and modest high-V neckline, basic cut without being too boxy.  Great color selection - just ordered 2 more!!
