If it is dress shirts it looks nice and clean if you tuck it in. But what about long sleeved cotton plaid shirts, should I wear plaid shirts tucked in or untucked with denim jeans? Is it ok to wear them to office untucked? it's a everyday dress down type office. And I'm 24.
It really just matters how long it is. I'm of the opinion that unless it's too short to stay tucked in, an untucked sport shirt looks really, really stupid.
