Short sleeve button down shirt
Size: XX-Large, Color: Navy Blue
These might run a size smaller. It still fit me but it is closer to XL than XXL in my case. It is great and comfortable as a casual shirt to wear out. It is easy to wash and dry, it did not shrink with cold water and just a tumble dry.

Comfortable, roomy fit and quality fabric
Size: Medium, Color: Flamingo, Size: Medium, Color: Flamingo
This is a comfortable, well-made guayabera (Cuban wedding-style shirt) available in a range of colors. It fits true to size on me, offering a little extra room to help you contend with the summer heat. The color and size hold up well in the wash; I've worn this shirt several times and it still looks great and hasn't suffered from any kind of shrinkage at all. I particularly like the linen blended with cotton here; linen is nice and light but can be too light sometimes and it wrinkles when you look at it, but the cotton balances it out nicely. The current discounted price of $20 a pop here is an absolute steal as well; I'm tempted to get another couple just to have some more options in my closet. Overall, I'm happy with this product.

Excellent dress shirt for the summertime!
Size: X-Large, Color: Navy Blue, Size: X-Large, Color: Navy Blue
This has rapidly become one of my top shirts to wear during the summertime, and it isn’t even summertime yet! Got this shirt in the other day and this shirt just checks all the boxes for me. It is comfortable in fact that it’s very comfortable. The material is not dry fit but it is not a material that will make you sweat the way cotton would make you sweat.. the fit is spot on, and it just happens to be one of those shirts (we all have shirts like this) where it is one of the go two shirts that you grab when you wanna look nice, yet you wanna be comfortable. Another thing I like about this shirt is the collar it doesn’t stick out too far and it just seems to fit in place the right way. Some collar on some shirts rest too far outside of your neck and some hug along your neck line, this shirt does neither of the two, it just fits perfectly. The material is very breathable allowing this shirt to be worn in any nice weather climate whether that is warm, hot, or that very sticky humid hot.. Another great thing to point out is I have washed it twice already and it keeps its nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is aAnother great thing to point out is I have washed it twice already and it keeps it’s nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is a steal of a deal, yeah I wish I had a closet full of these shirts with other colors.
