Heritage Auctions has a season 1 costume up for auction (from the Comisar collection) with a never seen surviving original top. The costume has replacement modern braids on the top and waist piece. The sleeves may not be original as well and is missing replacement braids as should be there.

An original seasons 2 - 5 top is included too and you can see the fine details on the tassels.

There's a purported Comisar season 1 bottle as well, but looks nothing like any seen onscreen (it has a black painted base instead of the leaf design painted on a bare bottle).
