Navy-colored top-style romper/overall combined with corduroy pants. The star-shaped hem is cute! I'm selling it because I don't like the pull-over type. Only tried on (just put it over the head), brand new and unused. It's size SM, but it should fit if your dog is 4kg and has a chest circumference of 40cm. The brand is 1milewalkies. Recommended for those who like Pet Paradise! Thank you for looking.
