I was able to put the bra and panties on Licca-chan by stretching them from her feet. I do not own a Blythe doll, so I am unsure about compatibility. I cannot answer questions about compatibility with other dolls. Thank you for your understanding. Due to individual differences in size, I cannot guarantee compatibility with unopened items. Please consider these items as being for Seria dolls. Please refer to the third image, which shows my personal Licca-chan wearing the same items. *The doll, underwear, and accessories in the third image are not included in the sale. Individual sales and price reductions are not possible. These items will be shipped via Mercari delivery. Please ask if you have any questions. #Torte's Doll Clothes
