Thank you for viewing! Please read the profile. This is a reversible, cold-weather vest!! It's warm because it's a combination vest of warm olive green gourd quilting fabric and fleece lining.♬.*゜ My dog wears it over his clothes when we go for walks^^ It fastens with snap buttons. Neck: 32-44cm (For dogs with a neck size of 40-44cm, they can't wear clothes underneath, it's, it's tight) Chest: 50-60cm Approximate length: 31cm Approximate front length: 21cm For dogs with long bodies, layering it will make the clothes underneath visible, which is fashionable. Are there any French Bulldogs that fit the size?❤︎ Please purchase with the understanding that this is handmade.
