Genuine Lindows OS Campaign Girl Costume Set + Bikini Inner

This is an authentic costume worn and used by a promotional model at the WPC EXPO 2003 held at Makuhari Messe on September 17, 2003, at the Lindows OS booth. Please check the following news article for details about WPC EXPO 2003:

This is an authentic promotional model costume that was specially given to me with permission from an advertising agency representative after the event ended. It is not stolen property or a for cosplay. This set includes the promotional model costume top and bottom, one arm cover, and bikini inner top and bottom. You can enjoy two different ways of wearing it. The costume will not be sold separately. The promotional model costume top and bottom are made of nylon and are water-repellent. The bikini inner top and bottom are made of fabric and are not water-repellent. AI models are used for the images of the female model wearing the costume due to privacy and portrait rights, but the costume itself is authentic. As WPC EXPO was later canceled and Lindows OS was discontinued, I believe this has high value as a historical document. How about using it as a Christmas cosplay costume for your girlfriend or wife? If you wish, I can also include the beige, all-through pantyhose that the promotional model actually wore.
Please check the product images carefully for the condition of the item. I am a non-smoker, so there is no odor.
The shipping method will be YuYu Mercari便 (anonymous shipping / seller pays shipping costs / free shipping) from Fukuoka City.
Thank you very much.
