Slip Dress Authentication Checklist
1930s–40s: bias-cut silk or rayon; lace trim at hem and décolletage
Look for delicate spaghetti straps with adjustable sliders
Check lace quality: hand-made vs machine-made significantly affects value
Condition issues: silk slips fray easily at hem and neckline
Identifying Authentic Rayon
Burn test: rayon burns quickly like cotton but leaves no ash — it just disappears
Rayon has a silk-like drape but slightly duller sheen than real silk
Label reading: "rayon" on labels from 1930s onward; earlier labeled "artificial silk"
Check for water spotting — rayon is prone to permanent water stains
Care & Preservation
Dry clean is safest. If hand washing, use cool water only — rayon loses significant strength when wet. Lay flat to dry; never wring or hang wet. Low iron setting.
