I love how versatile Yves Saint Laurent's strapless grey dress is; you can dress is way up or way down. Julianne opted to dress hers up with standout jewels, and sleek hair and heavy makeup. Model Audrey Marnay went a more understated route in leggings and tousled hair. I'm all for disheveled chic but Julianne sparkles. Whose side are you on?
