One universally flattering and never to go-out-of-fashion-scene color-pairing that happens to be my favorite too is Black and White. This is only color combination that is far from any age, color, race or physical limitations.
If you happen to be top-heavy ( like me ) then wear black on top and white on bottom and vice-versa in case you are bottom-heavy ( no offense to anyone ). Black is sure to camouflage any bodily lopsidedness and give the illusion of more balanced proportions.
Talking about white, so please care to wear this color all year round, be it pre/post Labor day / Memorial day ! White is fresh and flawless and who doesn't like to be clad in something as fresh as white, anytime and all times of the year. Then why even make fashion rules like no white after Labor day ????
So kick this fashion theory out the door, pair white with black and rock the most happening color duo.....!
