The gray one is from Nishimatsuya, and the pink one's brand is unknown. There are no quality tags. The gray one has barely been worn. It's brushed on the inside. The pink one is thin fleece, but it has a lot of pilling. Both have a very large waistband. There are adjustable buttons for the elastic. How about getting these cheaply if you're in your final month of pregnancy and running out of clothes to wear? These have been stored at home, so please only purchase if you understand this. Thank you.
