What should i wear with khakis?

i got a pair of khakis from Aeropostal, they are bermudas, but im not sure what to wear with them. I was think about a navy blue t-shirt to try to make it more casual, but i dont want it to look like some school uniform if its khaki and navy. i also thought about a yellow, kinda flowy, top, but like i said, i dont want to look to dressed up. im used to wearing jeans and a tee shirt, khakis are new to me :) any suggestions?
