This is a blue knit polo shirt. It looks great when worn with a white tank top, creating a very balanced look. It's also highly breathable, allowing you to wear it even in the middle of summer, despite being a polo shirt. The neckline is just right and won't overshadow your necklace. There are no noticeable fabric snags or yellowing. I bought it last year, but I haven't worn it this year, so I'm selling it. I will respond to any questions promptly. Please consider purchasing it.
