It fastens at the chest with a click, so it won't slip off and is easy to put on! The color is white. It's made of boa fabric, perfect for this time of year! I'm selling it because it's too small for my daughter to wear. It was only used indoors. It was hardly used even indoors. Apart from the black spot in the fifth photo, there's nothing I'm concerned about, but please refrain from purchasing if you are very particular about condition.
