engio got a reaction from willard in How Do You Make A Product Look More Expensive?
I was going to say textures when I read the title. You can also play with texture breakups, combine rough and glossy.
Color and material breakups if possible. For example you could use red stitches on black fabric instead of black on black.
Invert materials - for example leather can be outside and inside - by having the same material you get 2 different colors/finishes.
Although the best way is clever refined form to start with - it doesn't have to cost more to manufacture than ugly unrefined shape, even less.
If you already have a product your last resort could be new packaging or labeling.
