How can I create the "shop my look" link

hello! I am starting a fashion blog and I have noticed some blogs have an area where you can “shop their look”

an example of a blog that has what I am talking about:
https://weworewhat.com/2015/06/insta-beach-bermuda/

at the end of her post she has a section that says “shop these looks from my instagram below” with direct links to the site where anyone can purchase the items.

does anyone know how I can get this on my blog? thanks!
