Super hard to photograph this red. This is NOT a bright red but more like old glory red. 

Get your dog ready with this bold and adventurous Old Glory Red Stars Patriotic Sailor Bow! Made from high quality cotton, this Old Glory red bow features striking stars and elastic bands for easy attachment to your furry friend's collar. Perfect for celebrating the 4th of July in style!

large size is about 6 inches x 7 inches : perfect for any dog with 1.25 elastic bands ( average collar width) Msg me if you need a wider elastic.

small size is about 5 inches x 5.75 inches : perfect for smaller furry friends with the 1 inch elastic band.

as far as Human sizes go, I am wearing both sizes in the pictures!
