Stylists can add and delete products from lookbooks at any time.
Products' appearance in lookbooks is not a reflection of their availability. There may be products in your lookbooks that have sold out since your stylist initially added them.
If a product is no longer available from the retailer your stylist originally recommended, let them know and they can help you find it from somewhere else.
