    Great quality shirt, comfy, and loved the embroidery!

    Great quality shirt, especially for the price. The embroidery is fantastic. Ordered for a costume party, but is a great shirt for wearing out anytime.

    Well made but on the small side. I recommend ordering one size bigger than your usual size
    Size: Large, Color: Pure Black (Retro Rose)
    The fit on this shirt ran slightly smaller for me being a slim fit, so I order the next size up. Getting the next size up gave me a perfect fit. The material is soft and comfortable. I will likely consider similar shirts in the future. I recommend the product.
