The new Piperlime app makes you wonder where it's been all your life.

Now available as a free download for the iPhone and iPod Touch, this simple yet powerful app is powered by Shopstyle.com and includes apparel from Gap, Old Navy, Banana Republic and Athleta.

Shop for women's, men's and kid's shoes, clothing, handbags and jewelry from your iPhone or Touch and use the Favorites tab to save specific items.

A search function lets you narrow down your shopping list and there is an excellent array of goods to choose from.

And as always, shipping and returns are free (thank goodness).
