For the L*ve of the Game...
Color: Black, Size: XX-Large, Color: Black, Size: XX-Large
When I ordered this beautiful Thobe I noticed along with its minimalistic nature in looks that it took on, was the low price point... these dress garments usually run me a pretty penny in pastimes. It is soft, breathable & comfortable with a slender-like fit, all while being made of cotton and linen, which can be worn in multiple seasons... I ordered the black for a test run, and I am always on the look-out for (linen-cotton) around the clock (seasons)! And I am very pleased to report that I need additional colors because the quality of this garment is off the hook... and I want them all on MY hook! "WE WINN"

Fits great and works well in the hot summers - May order more in the future in other colors
Color: White, Size: X-Large
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!

Sizing not consistent
The pants was fine. The top was under sized. Overall quality was good.
