This is an open collar shirt I bought at GU a while ago. I like open collar shirts and bought this one, but it didn't fit, so I only wore it a few times and have been storing it at my parents' house. A dark gray short-sleeved button-down shirt, made of lightweight fabric for a comfortable feel. - Color: Dark Gray - Style: Short-sleeved shirt - Design: Button-down - Material: Unknown, but lightweight fabric Thank you for looking.
