Magic Cat OP from the Taobao brand Paltrystarshine in the pink colorway in size M. (It is a dusty pink/coral). This dress comes with 7 detachable bows, (with pins) and a detachable collar. It can be worn with or without the collar.

I am the second owner of this dress and have worn it twice. The original owner noted that one of the pom poms fell off a bottom bow, and they re-sewed it. The same happened to me with a different pom pom and I also re-sewed it. All original pom poms are secured now. This is why I have marked the dress as "modified" but otherwise there are no obvious flaws.

These are the official measurements from the brand:
Bust: 94cm
Waist: 82cm
Skirt Length: 92cm

Disclaimer: I own a cat, who is for the most part not allowed in my closet, I do my best to make sure he is not near my clothing but please be aware if you have allergies.
