I'm wanting some help with the title. I've recently bought a pair of chinos and they have came with a crease in the front. I've worn them already and kept the crease I was dressed pretty smart (shirt, blazer, pointed brogues) but wanted to know what people's opinions were on keeping the crease or ironing it out.

Would the crease work on a more casual level say with a pair of suede derby and oxford shirt or if I were to try rolling the leg and wearing with espadrilles/flip flops and a linen/cotton shirt?

Any help is greatly appreciated.
