In the Magic Kindom at WDW? I believe you'll be out of luck. Try:
Sandy Cove (Grand Floridian shop)
The sundries store at the Yacht & Beach (I think Fitting's and Fairing's Clothes and Notions @ Beach but not 100% sure)
The big World of Disney store in Downtown Disney
Lastly, if time is of the essence, you can purchase them before your trip by calling Disney Shopping and they can send you anything from anywhere in the resort. Disneyland has a similar service, and they may still be selling them from the Mad Hatter shop from that park. MouseShoppe sells the Groom hat online: http://www.mouseshoppe.com/directory.cfm?CategoryID=244
Maybe call them and they can get the bride beanie as well?
Which bride ears are you looking for? The ones my DH and I got while we were there was the blk top hat with the ears and the white (beanie I guess you could call it) with the ears.
We got those at MGM at a little shop on the left just before you get to TOT.
They also had them in the MK at Mad Hatters on Main St
I know some people here were looking for another style of bride ears that that a small head piece and the ears and a veil. Those I didnt see and I heard that they are only available at Disneyland.
