I'm Going to start with 10 Deep. Based out of NY, their lines drastically change every season and never let me down. One of the main reasons I like 10 Deep is because they have a real "tough guy" attitude. Many of their designs feature women, brass knuckles, and their logo with giant 'X's. Their lines are typical of Streetwear, T-shirts, Fitteds, Hoodies, and Jeans. They also release mixtapes with different artists such as rapper Wale.
Next on the list...
Mishka is another New York based Streetwear company with a different outlook than any other brand on the list. They focus on DJ, metal, horror, and punk culture. Many of their designs have a dark feel to them, due to their focus on the occult and obscure. They are beginning to receive a lot more attention recently and I imagine that will continue. They now have two other stores besides their flagship NYC store; one in Japan and one in LA. Mishka is on the rise, be ready.
Onto The Next...
G-Shock is not typical in the Streetwear realm. They focus only on one thing: Watches. A branch of Casio which has really made a name for itself in the streetwear market. You'd be hard-pressed to find someone in the streetwear game without one of these watches. You may be asking yourself how a company like Casio stay so relevant? They have a trick up their sleeve: Collaborations with major artists and companies known throughout Streetwear such as Dee and Ricky. Now, for something completely different...
Undefeated is one the best Streetwear brands in the game. Their focus on winning, sports, and being the best fit my personality perfectly. They are one of the best and they certainly aren't afraid to say it, or throw it in your face as they like to do. They have a variety of different clothing items and release a collaboration with a shoe company every season, which always sell out immediately. Their gear can be hard to cop though, it sells out quickly so if you want something, get it as fast as possible.
Finally...
Supra is a company which focuses primarily on shoes, they sell hoodies and t-shirts as well, but their shoes are their main attraction. Personally, I have three pairs in the closet as I write this. They have a variety of styles to fit everyone, from flashy gold shoes to your standard high-tops and low-tops, they got you covered. They are my favorite shoe company and never disappoint with their new lines.
