Can anyone give me some fashion tips ?

hey! don't be afraid to be labeled a nerd. wearing plain on-downs is definitely stylish if you know how to mix and match everything. like you said, you like converse and adidas. the simple original converse will do just fine. jeans is jeans! so go ahead :) as for shirts.. you can always wear white tops (t-shirt or tank)..and wear plaid on-downs.. use it as a cardigan or something.. you know what i mean? you don't have to on it. play with colors (trust me, you won't look like a r, emo or preppy and definitely not nerdy!)
