Queenie,
I saw the black patent pigalle 100 with the curved heel at BG last week (or 2 weeks ago). I am not sure if they will ship internationally but I don't see why not. You can try calling them, the number is 212-753-7300. The other pigalles that I saw there are black suede, wine/purple suede, and electric blue suede.
I also saw a brown python pigalle 100 with the straight heel (which I believe is very rare) at Saks this weekend. I picked up a pair because they are so pretty and suprisingly very comfortable, that 20 mm difference really helps.
