Only discounts available for bulk purchases! Measured with a measuring tape. These are approximate measurements. S size: Neck circumference 19cm, Chest circumference 36cm, Length 25cm Worn once when my dog weighed 1.8-2kg. It was baggy when she was 1.8kg! The pants are denim-style but made of soft fabric, so I think it'll be comfortable for your dog too. Please refrain from purchasing if you are likely to complain about minor details, as this item has been stored by an ordinary person.
