Thank you for viewing. My dog used to wear this, but it doesn't fit anymore. It's getting cold, so I think it will be useful from now on. It's 100% cotton. The size is indicated as 3S. ⚫︎I measured it myself with a ruler, although I'm not a professional. Please check the second photo. ⚫︎There are marks because it was clipped with clothespins for a long time. ⚫︎It's priced lower than the original price, so I won't lower the price even if there are likes. I apologize. Thank you for your consideration ( ͡° ͜ʖ ͡°)
