that looks like a good fit to me! itll seem a little odd looking, like it may be too big as its sliding down the neck, and this part usually takes the longest. mainly because their necks are so little compared to the rest of the body. youll want to see a bulge thats a little bigger than the body once it hits the stomach. if it takes longer than 10-15 minutes to get it all the way down, its probably a wee bit too big. if it takes less than 10 minutes, its too small. so 10-15 minutes is where you wanna look for. good luck!
