she won't wear it. It fits perfect but she freaked out and started running and flying all over the place trying to get it off. So...I took it off
It can take them a while to get used to wearing clothing. Some take to it immediately, others need time. Start out by putting it on very loosely at first. Hang around her for a bit so she doesn't get into trouble with it being on loose fitting. After an hour, try tightening it up a bit. She will get used to it eventually.
