Exclusive: Philip Treacy on designing Madonna's Super Bowl hat Watch Philip Treacy discuss Madonna's hat, plus his methods of designing. TelegraphPlayer_TMG9200192 The camera hones in on a note in Philip Treacy's studio: "Dear Phillip [sic]...We had an amazing night at the Brits. Thank you so much! We can't wait to intern at the shop. Love Gaga... That would be Lady Gaga, singer and crazy-hat wearer extraordinaire, who will be interning with the millinery king at some point (he's keeping schtum as to when). Pictures of her, along with Emma Watson and Pamela Anderson, all in his fantastical creations, line his walls. No sign of Princess Beatrice, though, who wore his infamous "toilet seat" hat to the royal wedding last year and got absolutely pilloried - funny that. READ: Lady Gaga: mad hatter "Generally, I like to start with a blank page and a pencil and see what comes out," divulges Treacy in the video made for the April issue of The Review , Harrod's online magazine. And then I edit and choose what I think would be right for next season. Treacy made Madonna's jewelled Egyptian-ish fanned headpiece for her Super Bowl performance. He shows off the mock-up he made of it, and, even as a dummy run, it's impressive. We make all of the pieces in 3D before we start, so we can judge on the proportions or detailing, so everything needs a mock-up.

It's about people putting their artistic expertise into something that makes the wearer look beautiful. If his outré designs float your boat, his new collection goes online at harrods.com tomorrow.
