Iridescent Mermaid Costume For Dogs - Large Closeout! Please measure your dog carefully and use the sizing chart/instructions as these brand new close out costumes are not returnable for size exchange :-) This charming Iridescent Mermaid Costume features layers of magical details, including a shell top and a coordinating shell headband adorned with a rhinestone jewel. Adjustable velcro chest closure, for a secure and comfortable fit Material: 100% polyester, acrylic rhinestone Sizing Chart: Size Neck Chest Length Large 17" 28" 20" All measurements are in INCHES. To ensure a correct fit for your pup, we recommend measuring Your Dog's chest at the widest "girth" just behind the front legs, then the back from base of the neck to the beginning of the tail. Chest sizes are almost always most important. If the garment won't fit their chest, he or she can't wear it at all. Measuring Your Dog then referring to the size chart is essential to determine your best fitting size. The weight is for reference as a estimated general guide only and is not part of fitting your Baby. _______________________________________________________ Notes: These costumes are not the "wear once and throw away" type of costumes. They are made very well and are designed to last occasion after occasion :-) Please MEASURE YOUR DOG! and use the sizing charts to select the proper size. Exchanges caused by 'not measuring' add lengthy delays and added costs for all. Thank You!
