This is a short-sleeved shirt. It has a denim-like color, but it's not as thick as denim. It's stylish to wear it casually over something, or to button it up and pair it with bottoms in a similar color for a set-up look ◡̈⃝ I think it's convenient to have one when you go out in a tank top, as it can get cold from the air conditioning in shopping malls and trains! It's also wrinkle-resistant and compact, so I recommend it ◡̈⃝ anap short sleeve shirt outerwear short-sleeved shirt shirt jean jacket denim jacket
