My favorites (like the most) for guys :

- Oliver People (nice sun glasses)

- Louis Vuitton (honestly I like the material, I have a wallet from LV since 1990, and it's still in perfect condition. Make sure you buy the 'Made in France' products)

- Etro shirts (most expensive and one of the best of its kind)

- Gucci (nice fitting, but six packs and slim figure is required, don't try to wear Gucci t-shirts with big bellies )

- Prada (good fitting shirts, love their belts and shoes. Prada make awesome shoes. I have like 6-7 pair of them. They also make very nice jackets)

- Prada Sports (very sporty stuff, especially their jackets and hats)

- Helmut Lang (just like Prada, but more edgy I think)

- Marc Jacobs (like the color combination and its disctinctive styles)

- Dolce & Gabbana (great shirts/t-shirts/jackets and sunglasses)

- Kenzo (sometimes the crazy design is great to be different)

- Michael Kors (good design and very different than other designers)

- Donna Karan (nice material)

- Paul Smith (another best shirt makers with colorful designs)

- Missoni (great design and not to overbearing)

- Jill Sander (classic but edgy and stylish)

- Romeo Gigli (distinctive material and color)

- Costume National (beautiful design and edgy)

- Hugo Boss (l like their color selection for suits)

- Thomas Pink (another great brands for shirts)

- Georgio Armani (classic and expensive suits, great materials and colors)

- Tod's (love their shoes for walking)

- Diesel Style Lab (great design, too funky at times though, love their shoes)

I'll think of some more from my closet
