length- 9.5"
girth- 11"
I hope this helps! I am not sure exactly how to measure it.
How big is Cali?
My Britney is 4lbs and it fits her perfectly, however she wore it a few times when she was a puppy and it fit her then. I'd say it would fit a dog who was 3.5 lbs to 5 lbs.
Let me know if I can help in any other way.
Edit: I added a picture of picture. She weighs about 4 lbs. I woke her from her nap so she looks a mess.
