And finally, what about the makeup or the hairstyle? "After all, no dressing up can’t be complete until you have done the right make up or done the correct hair cut. These are the two factors which can make or mar your face," says beautician Rita Mohan Toshniwal, who owns a chain of parlours in Kolkata.

Janet Jackson looks stunning in this white dress and minimal make-up.

This season straight cut is out for sure, and the curly, messy look is in. Go for shoulder length hair, which can be tied up.
