Thank you for looking! ´◡` The item on the left was purchased online, and the one on the right is pet wear from DAISO. Both are size L, but they were a bit tight. My dog is a Schnauzer, 6.5 kg (approx. 14 lbs). He has a thick chest. The left wear has front buttons and a small neck opening. The right wear has some pilling on the lining after washing. Both were worn 1-2 times and washed. Please understand that these are used items. Thank you!
