Brand & Neck Labels
Alexander McQueen branding has changed over time, and historical McQ diffusion pieces should not be confused with mainline. Earlier mainline labels commonly use the full Alexander McQueen name in serif typography; later presentations became cleaner. Authentication should compare the exact label family, garment category and era rather than expecting one neck tag for every decade.
Sui Generis approach: first establish the likely era and product category, then compare the wordmark/logo, label construction, typography and placement to documented examples from that same period. A genuine vintage label can be very different from the current retail label.
Brand labels, size tabs and care/product labels should be assessed as a set. For Alexander McQueen, expected construction can change by line and era, but the label materials, edge finishing, stitch attachment, printing/weaving quality, fiber/origin information and wear should be internally coherent.
A label that looks older than the garment, a pristine label on a heavily worn item, a care label whose language/fiber data conflict with the garment, or obviously re-sewn label stitches are reasons to slow down. Alterations can move or remove labels, so document tailoring evidence before concluding the label was transplanted.
