The phrase "exact dupe" refers to something that is an exact copy or replica of something else. It means that two things are identical in every way, without any differences. Full definition
Target sells an almost exact dupe for under $ 30, but I couldn't find it online. (wishesandreality.com)
And for the price, they are amazing, they are not exact dupes of the Kylie ones but these are a great addition to our lipstick collection!!! (itsjessiejane.com)
Also, if ya loveloveloved my leopard heels in this post, the boutique has a near exact dupe for literally a third of the price, and code COMINGUPROSES will work on those, too! (cominguprosestheblog.com)
