Type of Geta sandals?

Question:

I'm half Japanese, and my aunt bought me a pretty Yukata & obi~ but I didn't get shoes, so I have to buy them myself!

But, what kind? Obviously they need to match, but... I really like the kind with the 2 teeth, but all those I seem to find on Ebay say they're men's shoes... I see a bunch on ones for 'women' with rounded and flat bottoms, but those don't look really attractive to me...

Am I supposed to wear ones with flat or rounded bottoms~? ><

(Note: No, I can't ask my family~ They told me to just 'pick something no one will be looking at your feet!', so... xD Like I said, I prefer 2 teeth geta sandals... but, I don't now...)

Answer:

Your select is not so bad.
But I prefer more feminine one. I think a black strap looks to be for men.
How about this one? However I don't like the word "Geisha".
