Once you install the new Clipper (read instructions for bringing items into Polyvore, and see a demonstration), you'll notice that it works a little differently than it did before.
When browsing another website (such as Net-a-Porter.com or Gap.com, or any site you like), click the "Clip to Polyvore" button to open a dropdown in the upper right hand corner. When you rollover the image you'd like to import, you'll see a green border around it and you can click anywhere on the image to select it. Once you click on the image, a thumbnail of the item will appear in the dropdown - add some tags, hit "Import" and you're done!
The best part is that you can now import several items all at once! Your virtual wardrobe will be bursting :)
Check out the new clipper, and let us know what you think!
