... if you are looking for the all black large top hat with ears($99), Ive had trouble finding them too.
Those are discontinued. But if you have a pair of scissors you can make them yourself.
Bigheaded people like myself and groom can't fit into regular Adult earhats. I tracked down an inexpensive top hat from a costume shop, made two slices on either side, chopped up a plain earhat leaving some fabric flaps on each side, slipped in the ears and 'surgically' attached the flaps inside, with double sided tape. Voila! Top hat groom ears. Worked a charm! I wore the headband sequined bride ears for some after ceremony photos and at the entrace to our reception. We don't have any photos of his tophat ears unfortunately, until the professional ones come back. But I'm attaching some images of our baseball caps.
I did the same surgical procedure with two additional sets of ear hats on plain Bride and Groom baseball caps. His were plain back again. But for mine, I used the Princess

ears (pink hat, silver ears, with tiara and veil), making a third slice in the hat to slip in the veil, then at groom's suggestion, I stitched on the tiara. It was a little sad to butcher three new and perfectly lovely earhats, but the end result was worth it. And now that I can do this neat hat trick

, I can reuse the same plastic ears. I see many custom caps in our future...
We got a lot of compliments and questions from castmembers about them. Here is Aurora admiring mine.
