Hip online eyewear startup Warby Parker has, over the last two years, been partnering with boutiques to open "stores-within-stores," or small Warby Parker showrooms, where customers could try on their eyeglasses in 3-D. These showrooms popped up in L.A., Nashville, San Francisco and many others. Today Warby Parker officially announced its first, flagship retail store in SoHo in New York City.
