We saw black fringe swinging prettily as Agustina Lorenzo, 20, walked briskly across Avenida Santa Fe. We had to ask Agustina, an economics major, all about it. Turns out this porteña adds flair to a simple Ayres black shorts and white t-shirt combo—with some DIY fringe benefits. Kudos for showing initiative. And that adorbs red purse by Prune? Nice touch.
