You can check whether an item is in stock in your size by looking at the size underneath the item in the product list. If the size is written in black, the item is available in that size. If the size is in grey or not shown at all, it is unfortunately no longer available.
If you would like to know whether you can find the item at your local Zizzi store, you can contact the store directly. Find contact details for your local store.
Remember to tell us both the style number and the colour of the item you are looking for.
