You'll see the people who liked you by tapping the Likes You tab.
When someone likes you you'll see that indicated by the numerical badge on your Likes You tab. You'll see people who have liked you one at a time. You can choose either to match with them or to skip them.
With a Hinge Preferred Membership, you can see everyone who has liked you all at once by tapping on the gallery view in the upper right corner of your screen.
