Beaded cocktail dress with Oleg Cassini label

This is a vintage-style evening or cocktail dress featuring extensive simulated pearl beadwork on a cream or off-white fabric ground. The garment bears a fabric label reading 'BLACKTIE OLEG CASSINI' alongside a secondary tag indicating the shell is '100% SILK' and the lining is '100% RAYON', with a size '12' indicated. The design consists of a scoop or square neckline, long sleeves with sheer mesh-like construction, and a drop-waist silhouette. The beadwork is arranged in dense linear patterns around the neck and waist, with scrolling filigree motifs throughout the bodice and vertical beaded fringing or rows on the skirt. While the labels suggest a late 20th-century manufacture (likely 1980s or early 1990s), this attribution is based on the visible tags which have not been verified for authenticity. The dress appears to be in good vintage condition, though close inspection would be required to identify missing beads or snags in the delicate silk and mesh. The sheer sleeves and heavy embellishment are stylistically consistent with the 'Black Tie' evening wear line produced under the Cassini name during that era.

I have examined the images of this beaded evening dress. Based on what I can see, the garment features a label consistent with the 'Black Tie Oleg Cassini' line, which was a prolific mid-to-high-end evening wear brand during the 1980s and 1990s. The design exhibits a 1920s-revival silhouette popular in the late 20th century, characterized by the dropped waist, sheer sleeves, and extensive faux-pearl and glass beadwork on a silk ground. The construction appears high-quality; however, I cannot verify from a photo the structural integrity of the mesh or the presence of specific bead loss, both of which are common in garments of this age and weight. The estimate assumes the garment is in good to very good vintage condition. This value is based on the working hypothesis that the attribution to Oleg Cassini is correct. Such garments currently enjoy a stable market among vintage collectors and for special occasion wear. While the labels appear consistent with known examples from this era, physical inspection by a textile expert would be required to confirm the fabric content and label origin. To confirm the piece's history, one would need provenance documentation or a professional authentication of the garment's construction techniques. If this item were determined to be an unbranded 'in the style of' piece or a later reproduction lacks the Cassini label, the market value would likely decrease to the $75 - $150 range. Conversely, if it is a well-maintained example of this specific designer's late-century output, it represents a desirable piece of wearable fashion history.
