I tried the bee outfit on my cat once, but she doesn't like clothes, so it was just a try-on. Both outfits have been washed once (without fabric softener). Both are size S. I've included the size chart from when I purchased them, but I've lost my measuring tape, so I don't know the exact measurements. I won't be able to measure them if you ask. As a size guide, I've included a photo with a standard pen for comparison in the third picture. I hope this helps. The bear outfit is a bit smaller than the bee outfit. There is some stretch in the neck area, but these are sizes for smaller pets. It fit my 4-month-old kitten perfectly.
