Very vibrant colors and quality materials. Pay attention to the size, the XL is narrow (Slim Fit) and it fit me comfortably without being tight (I usually wear medium to large). The material is quite good for its price and it can be combined with chinos and a blazer or jeans and a leather jacket.

I bought it in turquoise, navy blue, burgundy, and white. As for durability, I will have to come back to that, but for €20 per piece and lasting 6-8 months with office wear and outings, I will be satisfied. If I wanted something to last for 5 years, I would go for GANT, Ralph, Hugo, Lacoste, but they cost 4+ times the price.

Lastly, you don't need a shirt underneath, it doesn't itch, but during winter, a slim fit long-sleeved shirt to keep some warmth is needed. It's not warm enough for walking in the snow in Arachova.
