Where to shop in Baltimore for men?

I am 23 year old, I have a very chill style. I like sean john, roca wear, enyce, polo, lacoste, the new miami ink shirts, just a whole mix of things, I guess you will say urban style meets the preppy kids. What clothing shops are available in B-more and DC for me to shop at or are there any flea markets around. Thanks|||I like Army surplus clothing so I shop at The Old Navy Store.
