I finally found my tape measure and the measurements actually match up with the official measurements from Louis Dog.
Neck 9.6" Chest 13.6" Back 8.8"
Unfortunately at this time I am not wanting to trade, just sell. I am trying to downsize my doggie closet because each drawer is overflowing

I stopped counting the outfits once I broke 100. I quickly glanced at what has not been worn at all or what has barely been worn and pulled it out to try to sell. I'm sure more will come out soon once I have a chance to go through each drawer. I'll probably be back on the purchase train soon because I am a sucker for high end doggie couture
