Vintage Barbie Golden Evening #1610 (1964)
 
Gold Knit Top
Gold Knit Long Full Skirt With Gold Glitter
Gold Dimple Belt
Gold Charm Bracelet
Mustard Open Toe Heels

While this is not a difficult ensemble to find, it can be hard to find in excellent condition and with a lot of the glitter remaining on the skirt.  This is the same top as the Knit Top from the Knit Mix & Match Group Fashion Pak (1963) and the skirt is the same as the Knit Long Skirt from the same group.  The hardest piece to find is usually the charm bracelet.  The mustard color open toe shoes were not included with any other ensembles, but were included in shoe paks.
