Hi 20somethinggirl,
I agree with Nick, that eBay is a great source for finding nice leather gloves!
Don't you have any leather riding gloves in your size? Just wanted to check!
If you wish to look for some nice leather riding gloves, I can suggest both eBay UK and eBay Germany. If you want to look for them at the German site, use the search term: lederhandschuhe, or leder reithandschuhe. (You can use the first term and then look under Sport. When you have gotten that far, you can use the menu on the left side and click on the link: Reit- & Fahrsport, which will give you a more narrow collection of hits!
I can also suggest you look for the brand names of Roeckl as well as UVEX or Schwenkel, as those brands make high end products for riders! Good luck!
