Founded 70 years ago by Ralph Ostrove (the shop is named after his son), this upscale menswear store has been keeping guys from every walk of life well dressed, whether they be businessmen, rappers or grooms on their wedding day. Walk through the doors and you can tell that the brand is all about preppy, conservative, no-nonsense, Chuck Bass-esque style, from suits and sweaters to ties and outerwear. Don't feel left out, ladies—there's a women's shop upstairs now, too.
