To add inventory to a Party, your items must first be listed. To list your items, go to your Inventory page. You can list your items by style. Select the items, scroll down and click List Without Posting to Facebook. This will move your items over to your Manual Listings page.
You can click the Menu button to the right of the Party name, and click Manage Items, which will allow you to add inventory by size and style, or add your entire listed inventory.
If you would like to be more selective on which items you would like to add to the Party, go to your Manual Listings page.
Select the items you would like to add to the Party, scroll down and click Add Selected to Party. Select the Party name and confirm.
You can find the Party link by clicking the clipboard icon next to the Party name, which will copy the link that you can paste at your convenience.
Or, to view the Party link, click the Menu button to the left of the Party name, and click Manage Approvals. At the bottom of that screen, you will see the Party link.
