Please see pictures for best description, I am happy to answer any questions the best I can. From a smoke free home

This was used for about 3 minutes for pictures and put back in the package. The bag says for small to medium dogs but as seen in the pictures I put it on our dog who weighs 97 pounds and it fit just fine, is stretchy so will fit small and larger dogs, I would suggest only using for pictures or quick dress up time, it is lightweight and adorable for pictures.. Below is some information from when I purchased it.

The collar is made of red ribbons with small heart shape that create a fun; the heart headband is made of soft cloth with bling sequin love hearts, red feather make your pet more attractive and dynamic in crowd!

Don't leave your dog out of the festivity, include them in with this heart headband and collar.
