Hello and welcome to SaleHoo,
Their clothes are so cute! And looks like many are into it as well.
Unfortunately, I have been searching for several hours for CIKICOKO (main website) and I just can't seem to find it. I found a few Chinese links like to Aliexpress, but it would be a bit of a challenge to vouch for those listing as I haven't dealt with them.
I did see a few listings from Link hidden: Login to view
although I doubt the authenticity of the brand name, but in case you are interested you can try and check it out.
Sorry I was not of much help here...
