The answer is: really cool underwear! I like to wear briefs and I like them comfortable and with some sense of design.
The vast majority of the ones I have are from Calvin Klein, but, as you can see in the picture, I also own other brands, like: 2(x)ist, Unico, Zara, Diesel, Benetton, Perofil, Dolce & Gabbana, AussieBum, Manstore, Unno, RGSBIKK, Bike, Evolve, David Beckham for h&m, puma and Wood.
Today, on top of my underwear, I am wearing skinny jeans by gap, t-shirt by TopMan, cardigan by Forever 21 and shoes by adidas.
