Monkey Daze Designer Dog Apparel - Teddy Bear Striped Skirt - Color: Red, Size: XS For sizing chart, click on the other images link above. We recommend one size up for comfort if your dog's measurement is the higher end of the range listed. Please note that these lengths represent the size of the dog and do not reflect the actual length of the garment. Sizing for each dog is unique. Similar to our clothing and accessory, medium size from one designer is not the same for another. For example our 9-pound yorkie model usually fits either one of three sizes (i.e. XS, S, M) depending on the designer. We highly recommend you measure your pet precisely with a flexible tape measure to ensure the best fit. Contact us if you have question. We are happy to help. This one-piece is made for comfort, style and will stay put. Very cute mini teddy bear at the back. You will not be disappointed with the detail and the designer look.
