I prefer casual style clothes, so if it's polo shirt then Burberry, Lacoste, Tommy Hilfiger, Ralph Lauren.
For t-shirts I prefer to go with something simple, like Hollister, Ellesse, maybe Raised by Wolves, sometimes I wear adidas tees.
For jeans, I always go with Guess bcuz I really like their jeans but Levi's is great as well. I also have one pair of True Religion jeans but those cost like 300€.
If we're talking trainers then adidas, Nike is fine as well, but I prefer adidas to Nike.
Finally, shoes. I always go with adidas. I have some pairs that have boost, like Iniki and XR1, but I prefer vintage silhouettes. Samba x CP is my favorite pair atm, but I also own Topangas, Campus ADV, Jamaicas, EQT 93/17, and as I mentioned before, Iniki and NMD XR1
