Vintage Disco could be either 70's, 80's or 90's. I believe it is 70's because of the detail on the sleeves. and the closure.  Red Silk heavily beaded mandarin collar dress/ top  with red and silver bugle beads.

High Mandarin collar neck - chiffon see through key hole-ish chest with beading all around.
Flaired skirt 

Long beaded sleeves with button closure and silver bugle bead edging

Key hole back 

Looks like it could be Ice Capades dress/top. - Please check for length.  dress is only 30" long

The dress is in very good condition and considering age etc. There are only 2 loose strings with minimal missing beads.  I have photographed.  But it is really hard to see any blemish in the picture as there are barely any beads missing.
