Nelle I love ballet flats too. There is a funky little shop in Montville that has fabbo ballet flats & I just might () have a few...

I got this season (only about 2 months ago) a pair of black patent flats made by Zensu. They have a bow in the same leather across the top. They were about $120 (but I got them during a buy another & get 30% off them both sale - so I got two!).
They are square toed but not round like yours & black patent. I got them from Mathers.

I also have a pair of purple patent by Diana Ferrari (Supersoft) that are round toed with a gold buckle across the top. They were a bit cheaper but super comfy too. I got them from Myer.
