    Quality meets style
    Color: White, Size: Large, Color: White, Size: Large
    This is an Oxford button-down dress shirt that is a great example of quality craftsmanship paired with classic style. The 50% polyester and 50% cotton fabric has a nice substantial weight to it that feels durable without being too heavy, making it perfect for a polished summer look. The detailed design around the collar adds a subtle touch of casual sophistication, and the chest pocket keeps it practical and versatile. The construction is impressive, with securely attached buttons that reinforce the overall sense of durability. I also appreciated the inclusion of two extra button which is a thoughtful and useful addition. The size large did run a bit snug so I’ll be ordering the next size up. This is a well-made shirt, of a quality-feel material. This brand continues to deliver on both quality and style, and the price feels more than fair for what you’re getting. Overall, a very nice summer dress shirt that I’d gladly recommend.

    No flaws, not high end
    Color: Pink, Size: Medium
    I nabbed this for my in shape 14 year old son who had an upcoming wrestling banquet. It fit very true to size for him however as a low-mid grade dress shirt it had little flex or mobility across the chest and that’s ok, this is an entry level dress shirt and perfect for this and similar events. The color was vibrant and well saturated, and the fabric itself was thin enough for some transparency but thick enough to be considered medium weight. It would not be a cooling dress shirt. It did not have a soft hand, rather a sturdy rougher feel akin to a dress shirt a restaurant server would wear and laundry frequently which is also ok because it is exactly what a polo in this range should be. If you are looking for a flexible chest and soft touch you will need a better fabric blend and you pay a lot more for that. The buttons were nice and collar looked good. I would recommend this for any average event or occasion or even for work. If you are looking to impress on an interview or a date or during high heat you might need to look elsewhere. For what it is it’s perfect. Buyer and shirt need to remember this and keep it in its shirt lane.
