I received this, but the timing and size didn't work out, so I only put it on my pet once indoors to take a picture. It's super cute, so I'd be happy if someone liked it. The white outer side is made of boa material, and the pink part is a crinkly material like a windbreaker. The striped pattern on the inside (the reverse side of the reversible item) is made of cotton fabric. It's in beautiful condition as it's close to unused, but please refrain from purchasing if you are concerned as it has been inspected by an amateur and stored at home.
