All Black Everything
Every person out there probably knows that black clothes come with a slimming effect. However, you should be aware that it can wash you out as well. Skin usually gets lighter the older you get, so you need to be careful with this color as you age. Make sure to balance things out with a touch of bright color.
Tweed
You should avoid tweed unless you are trying to look a decade older than you really are. But then again, we doubt that anyone wants that to happen. This is a material that only looks nice on little kids and folks in their nineties. If you like menswear, you are going to look better in pinstripes and houndstooth.
