Would you guess 18? I wouldn’t. Although I suppose only a teenager today would consider telephone wire sufficiently passe to count as a “vintage” accessory. But she’s giving off a vibe that’s somewhere between Jessica Simpson and Mrs. Robinson — both curiously domineering, yet swaddled in an outfit that isn’t terribly well-styled, makes her look burlier than she probably is, and gives her an aura of being overeager for your respect. Honey, you’re eighteen; you have your whole life ahead of you to look old. Want to trade? Because I’ll do it. I’ll really do it.
