Miley Cyrus with wedding dresses

I was going to write about wedding dresses, but an eyeful of Miley Cyrus at the Academy Awards and I knew just what Xtabay's followers--heck, everyone--needed to hear. It's simple and free and makes every outfit look immeasurably better: Stand up straight.

I know! You've heard it a million times from your mother. But posture really does matter. You probably saw Miley slouching up to the microphone, looking as if she was afraid if she stood up her dress wouldn't make the jump with her. She looked tentative, uncomfortable. Now imagine Lauren Bacall striding across the stage. She moves tall, with confidence, exuding a panther-like grace.
