Description
Trigonometric DelightsA fun, entertaining exploration of the ideas and people behind the growth of trigonometry. Trigonometry has a reputation as a dry, difficult branch of mathematics, a glorified form of geometry complicated by tedious computation. In Trigonometric Delights, Eli Maor dispels this view.

Must iron first before wearing. Then wrinkle free.
The fit is perfect. The material is quite nice. The only problem would be they are hard to de-wrinkle from original packaging. I’ve washed my shirt several times and it’s still showing the creases. The only way to get rid of them is to launder them or iron them. I think once this occurs, they remain wrinkle free for a while. This is the third of the exact same shirt I got in different colors.

Nice quality shirt
Color: Purple, Size: XX-Large
Nice material and fit is accurate. However shirts are rolled up in a tube, so if you need to wear the shirt the day you receive it be prepared to iron it!

Calidad de las camisas
Color: A White, Size: Medium
I had already bought one shirt, so this time I bought two more. The light blue one is the same quality as the one I bought the first time. But the white one wasn't the same quality. It was also a different shade of white. They should try to maintain consistent quality across the board.
