Bandanas are made to fit right though your pup's collar! For the best fit get the same size bandana as their collar size.
Each bow tie and headband is attached to a elastic band to wrap around your pet's neck/head. Please measure your pup's neck or head circumference with a flexible measuring tape or simply using a string and a ruler. This is to ensure an accurate measurement so the bow tie or bow headband is not to tight or loose.
