Vintage dress question.?

I recently bought a vintage 'Fredericks of Hollywood' dress, and I want to know when it's from. It's mainly pale green with other pastel coloured plants on. The bodice is strapless, ruched and boned and the skirt has two tiers. It finishes above the knee and the label is white with purple stars around the 'Fredericks of Hollywood' logo. It also has some small panels of elastic shearing on the back. Thanks :)
