If anyone has got any of her costume stuff, it might be the V&A museum. They have textiles older than Eliz I. ( cf the Syon Cope, etc ) Or just possibly Hampton Court . Gloves are the most likely to have survived, especially as they were often given as gifts. Some courtier may have treasured just such a gift and passed it down to his/her family.
Mind you, she didn't exactly have dresses/frocks. Costumes were made up of separate items, and bodices would be separate from skirts and underskirts, and maybe sleeves would be separate again. Then add a ruff, hair decorations, trains, cloaks and more - and it's quite hard to say what would count as a "dress" in those days.
