Like all Girelli Bruni apparel, this T-Shirt is also exceptionally crafted. No misplaced stitches or loose thread anywhere. The collar is not too wide for slim persons like myself, and the tags were easy to remove without damaging the shirt. For sizing, I'm 176cm tall, with a slim build and a 96cm chest circumference, and the 48 size fit me perfectly. As for the fabric, it's a lightweight material so is slightly see-through. The Giza cotton used in this shirt is very smooth and has a slight lustre to it, so it looks luxurious. It's not as lustrous as Suvin Gold or mercerized cotton, though, so don't expect a lot of shine from it. A couple of suggestions I would recommend to the GB team for this shirt is to make it in a slightly thicker jersey so that the material is not as sheer (the shirt becomes slightly see-through in bright daylight). And to make the collar a bit thicker and sturdier too, so that it retains its shape after repeated wears.
