The Service: Within the PS Dept app, you can send stylists from a variety of retailers (including Moda Operandi, Bergdorf Goodman and Opening Ceremony) a message or image—or both!—of something you're looking for. They'll get back to you with in-store options to purchase from your phone.
The Cost: Both the app and service are free (unfortunately, the clothes are not).
The Commitment: Because the app was created for busy women who have no time to shop, the process is quick, easy and painless: the only work your end is picking a good inspiration picture and clearly articulating your needs. After all, the better you explain what you're looking for, the more likely a stylist is to find it!
