Cargo or nogo?
There is a fine line with cargo pants. Too casual and you look like you just got the high score in big Buck Hunter. Too styled and you can look over-the-top sartorial. Find that balance. Here are three options grounded with complementing indigos.
Destructed denim is a rugged layered look. I don't think Gap sells the paint splatter jacket anymore, but that isn't something a little can of paint and your brother's toothbrush can't fix.
A rinsed denim or indigo shirt for a cleaner but casual look. This also works with a white oxford.
Preppy florals with a cargo is unexpected and stylish. As long as the colors are jiving you can go for it. Quick tip, indigo + olive always works.
Beat it, kid. These aren't the cargos I was trying to get at.
