I bought this supercute Lady Gaga'esque clip-in hair bow from Claires Accessories for £5. The colour match is perfect for my hair. It is also available in brunette and black. They also have them stuck on to headbands, but the clip-in one is more realistic.
Photo is at a friend's wedding. My dress is from Asos.com, my Bambi necklace is from Disney Couture and the bouquet is the bride's :)
