Not sure where you live, but it would be worth checking out your local museum for inspiration cause many of them have clothes throughout the ages. Even if they are not on display the curator may let you have a look through the storage areas and get photos to add a great 'local' angle to your project - many of the clothes are usually donated by local people. Again, it depends where you live, but if you're near a big city you might be in luck (Preston and York museums have good fashion sections). Good luck with the project!
