Hmm, no I have never seen these anklets or I would have bought them as I sell lots of wristbands and the girls always want anklets.
I looked all over Thae Phae Road for silk old silk dresses and they were very difficult to find. I bought one and ended up giving it to my mother as people here are too cheap to appreciate silk.
Guess I didn't pay so much attention to the dress you had on there but it looks more like native wear from Chiang Mai. I like them but mostly the Asians wear that style and not so many Americans. Personally, I like the Lanna style.
Best suggestion I could give you is to develop an website and to try and market your designs there as you can reach worldwide with little expense of having to maintain a shop
