A wide range of doll wear is currently available by many third party makers. The dress that Kizuna is wearing here is by
Iple House for their YID - Girl series which is roughly the same size as Smart Doll. Here Kizuna is fitted out with a Large Bust. You can also try out some of the following doll wear makers below and seek stuff that would fit a 60cm tall doll.
Please be aware that Smart Doll has large hips, long legs - even our S bust has a wide circumference.
