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 burgundy quilted fabric and fleece on the inside. ✨️ My dog wears it over their clothes when we go for walks ^^ It fastens with snap buttons. Neck: 34-44 cm (Those with a 40-44cm neck can't wear clothes underneath, it's, it's tight!) Chest: 50-60 cm Approximate length: 31 cm Approximate front length: 27 cm Are there any French Bulldogs that fit? ♥ Please purchase with the understanding that this is handmade.
