Looks and feels great - very breathable in the hot summers with the Cotton and Linen blend. It felt a little rough at first but after washing it it feels wonderful (and it did not shrink!). It fit well and the size is true to what the table shows. It felt a little long at first but I got used to it very quickly. It's comfortable when going outside when it's 80+ F outside. This seems like a quality product and I hope it will last for years to come. Within the next few months of summer, if I really like after wearing it a few times I might order some other colors!

Used for a photo shoot and it looked Great! Very impressive quality for the price. Cut on the slim side and looks a bit retro
