Vintage 1970s Givenchy Nouvelle Boutique

Vintage Givenchy Nouvelle Boutique top. Zip closure at back and sleeve cuffs. The base material is sheer black with square gold sequin-like embellishments throughout. No fabric or size tag, but fits like a US small in my opinion. Laying flat, it measures approximately 18 inches across just under the arms, and 24 inches shoulder to hem. Some missing/lifting embellishments throughout, but because it’s so reflective, in my opinion it doesn’t impact wear. The same vintage style has previously sold at 1st Dibs for $800. See photos for details. Edit: I previously thought this was a 1980s piece, but after looking at some other vintage Givenchy labels and pieces, I believe it is probably 1970s - though I’m not 100% certain.
