If any brand is more than happy to celebrate Prince William and Kate Middleton's marriage, it's got to be the 'Royal Wedding at Liberty' collection.
Whether it's fridges or condoms, the Royal Wedding at Liberty series of products pretty much covers every other accessory you can think of. Items range from shirts, mugs, canvas tote bags to key chains. The tea bags are probably the most entertaining as they depict the royal family in a seated position so that when you put them in the cup, they look like they're chilling in a hot tub.
Depending on the type of memorabilia you want, I think the Royal Wedding at Liberty collection will provide a nice variety of products to celebrate the monarch nuptials.
