It has also added a couple of new features to help out in your holiday shopping search. There are now custom product wishlists, expanded Gift Guides from famous users, and even a new way to save items from Gift Guide displays.

So, first off, Pintrerest has added an easy way to save items to your own holiday shopping wishlist. This is where you can collect together things you like, for yourself or somebody else.
Now you will be able to save products directly to your holiday wishlist, so you can easily reference them throughout your shopping process.

Pinterest has added the feature to quickly save things to its celebrity-curated Gift Guides, which will also share your saved Pins into your very own shoppable wishlist.
I don't know how Paris Hilton keeps getting herself highlighted in social platform activations, but there you go, if you are into pink and quasi-celebrity DJs you could check out what Paris thinks is cool this year among many others.

According to Pinterest

With over 1,000 unique gift guides around the world that are curated by creators and celebrities like Paris Hilton, RuPaul, Emma Chamberlain and K-Pop girl group TWICE, Pinterest is the go-to destination to find a gift." 

Now, you will find it easier to save items from these collections recommended by celebrities, which would be added to your own in-app wishlist.

Finally, Pinterest is introducing a new, machine-learning-driven display of personalized Pin picks to its "Holiday Finds" tab, which it said will show items that its system thinks you would like.

"This feature is experimental and will roll out over the next few weeks. This special shopping experience relies on unique searches and saves to suggest relevant styles and ideas that are must-haves for the holidays.".

So, a personal list of Pin products based on your past activity and interests. That's an easy way to spot really relevant gift ideas that you might hint at family and/or friends to get for you for Christmas.

Pinterest is continually adding listings to its products, and constantly evolving algorithms for product discovery and recommendation. So it should remain a good source of ideas for gifts during the holiday period, while celebrity-curated product listings will also become a strong draw for many fans.
