“Comfortable but does fabric pill?”

“At first glance, I saw slight pilling, both inside and outside of the shirt. [...] Now I think it's because the fabric is a "brushed" polyester, which accounts for how soft it is. This fabric is very comfortable against your skin. The construction is tapered in at the torso, but not form fitting. I intend to wear it for yoga or other fitness exercise at home. I've washed it once, and the shirt held up well. I think I'll like this better than my first impression, but I'm giving it only 3 stars, because I'm doubtful about how much further the fabric will pill.”
