Hi,
From a buyer's stand point:
Sizes vary from country to country. When viewing the items for sale in the "List" or "Gallery" fomat it would be nice to see the country where the seller is located. Perhaps place the country in the "Seller" column located on the right hand side of the page.
This would save time in determining which sizing method is used. It would make it easier to determine if items are the size that you are looking for without opening the auction or going to the About me page. Much easier for scanning in the "List" and "Gallery" formats.
Example of Women's clothing sizes in different countries:
US and Canada: sz 2
Europe: sz 32
UK: sz 4
Australia: sz 6
Japan: sz 5
If an auction from the US said size 2, and the seller's country (US) is listed under their name in the "list" and "gallery" format, I know I am looking at a size 4 (UK) without clicking to another page to get the country of origin.
Thanks for your time and consideration.
