Results: Why Can't I Find Additional Clothing For Barbie's Siblings?

As a kid, I had all the Barbie doll characters & additional clothing was available to purchase for each of them. My granddaughter is now into Barbies, but I cannot seem to find additonal outfits for the siblings (except vintage ones on eBay). Are you familiar with the Barbie doll's siblings (Stacey, Chelsea, Skipper, etc.)?

Have you tried to find additional outfits to purchase for them?

If so, were you successful?

If you were successful, where did you find them?

Do you know if patterns are available so that I could make my own clothing for them?

Any suggestions??? Thank you!
