Fabric Concierge: Help me recreate this look

This is a luxurious burgundy velvet blouse with romantic Victorian-inspired details - ribbon ties at the neckline, gathered waist seam, and full sleeves with fitted cuffs. The rich jewel tone and dramatic way the fabric shifts from deep burgundy highlights to near-black in the folds is classic velvet behavior. <!--concierge:{"bestGuess":"Viscose velvet or silk velvet. The fluid drape and soft gathering at the waist indicates this isn't cotton velveteen (which would be much stiffer). The way the fabric flows and pools, combined with the uniform pile texture visible in the close-up, suggests viscose velvet is most likely, though silk velvet would behave very similarly and can't be ruled out from photos alone.","options":[{"fabric":"Silk velvet","price":"Investment","pros":"The most luxurious option with incredible drape and subtle pile irregularities that create depth.","cons":"More expensive and requires careful handling and dry cleaning."},{"fabric":"Viscose velvet","price":"Mid-range","pros":"Offers beautiful drape very similar to silk with uniform pile and rich color saturation.","cons":"Can be delicate when wet and may require special care."},{"fabric":"Polyester velvet","price":"Budget","pros":"Most affordable option that's easy to care for and maintains color well.","cons":"May have a slightly more artificial sheen and less breathable than natural fibers."}]}--> What fabric do you think this is? Any suggestions for recreating this look?
