1000% authentic. Worn once. Sheer stretch fits size S. From the Spring 2018 collection. Hype beast even wrote an article about the drop of this particular piece in the Givenchy collection. Ultra sexy, neutral nudes with huge “Givenchy Spring 2018” metallic lettering across it. Overall flawless aside from a small hole in the left armpit where the stitching came out, but this is easily repairable. Only ever worn with full underwear. No stains, no pulls. Incredible piece. Bought for $980. Posh authenticates over $500.
