A stock update will be displayed when you select the size/colour you require on the product page. On certain items we're unable to ascertain an exact date and therefore advise an estimate of 2-4 weeks.
If an item is out stock you can sign up to be notified when it comes back in, more information on this can be found here.
Please note: when the size/color of the item you are after is not displayed it is likely that this is discontinued or no longer available.
If you need further help with this or a personalised recommendation for an alternative product, please chat with us and we'll be happy to help.
