These are single-layer undershirts purchased for a baby born in December. They should fit anyone expecting a baby soon. All are size 50-60. They have ties instead of buttons. Detergent: Sarasa. Fabric softener: Unused. No smokers or pets. Second photo: White, HOT BISCUITS Third photo: Cream, Akachan no Shiro (Castle of Babies) Fourth to sixth photos: I forgot where I bought them. Probably Akachan Honpo. Thank you for looking. If you don't need five, I can adjust the number.
