Occupation: Fashion designer
Claim To Fame: If you've ever spotted a flawless, need-to-have-it frock from across the room at a soiree, Alexandra was probably the one who created it. She's the founder of Markarian, the label beloved by It Girls and socialites around town. She became a national household name, however, when Jill Biden wore her custom designs to her husband's 2021 inauguration.
