Dating clothing by the hem
Hand-rolled, blind-stitched, horsehair-braided, weighted with chain — the hem of a garment is a small craft history. Reading it dates the piece and often identifies the maker.
The hem is the most visible interior finish and the one most exposed to wear, so it is often the most carefully constructed part of a quality garment and the most replaced part of a worn one. Original hems date and price a piece. Replaced hems indicate alteration, sometimes substantial.
Hand-rolled hem — the couture default
A hand-rolled hem is the finest finish for silk chiffon, fine cotton lawn, and similar lightweight fabrics. The technique: the raw edge is rolled tightly between thumb and forefinger as the worker hand-stitches it in place. Done properly, the rolled edge is invisible from the front, and the stitches are tiny (12–20 per inch in couture work) and evenly spaced. A hand-rolled hem on a chiffon evening dress is a strong indicator of couture or near-couture construction, and the workmanship persists across all eras from the eighteenth century to today.
Blind-stitched hem — quality ready-to-wear
The blind-stitched hem (also called slip-stitch hem) is folded under and tacked with stitches that catch only one or two threads of the visible fabric. From the outside the stitches are invisible or nearly so. This was standard quality finish across most twentieth-century ready-to-wear; finding it on a piece that otherwise looks utilitarian is a sign that the maker cared about finish.
Horsehair braid hem — for fullness and weight
A stiff braid (originally made from horsetail hair; now from synthetic stiffening) sewn inside the hem to give it body. Standard on Victorian crinoline-era skirts (the braid helped the skirt hold its dome shape), revived for the 1947 Dior New Look (the 1947 'Bar' suit jacket has horsehair braid in the hem) and used throughout the 1950s circle skirt category. Modern theatrical reproductions sometimes substitute thick interfacing; the genuine horsehair braid has a distinctive open weave and a specific stiffness.
Weighted hems
Couture evening pieces from the 1930s onward sometimes have small lead weights or chain-weights sewn into the hem to make the skirt fall correctly when standing or walking. The weights are usually small (a few grams each) and concealed inside the hem allowance. A 1930s bias-cut Vionnet gown often has chain-weights at strategic points around the hem; a 1947 Dior coat has lead weights in the hem to hold the drape. Modern reproductions almost never include weighted hems because the labour cost is prohibitive.
Machine-topstitched hem — the mass-market signal
A hem finished with visible machine topstitching on the right side indicates mass-production from the 1960s onward in most cases. Earlier mass-produced garments still typically used blind-stitched hems because the labour was cheap enough. The 1960s and 1970s saw a transition where topstitched hems became acceptable; by the 1980s, topstitching was standard. A topstitched hem on a 1950s 'cocktail dress' should prompt close inspection — it is more likely a 1980s reproduction or has been hemmed by a later wearer.
Serged hem — recent mass-market only
A serged (overlocked) hem — the raw edge is bound with a zigzag machine stitch and not turned at all — indicates 1970s onward and almost always mass-market construction. Quality post-1970 pieces still use turned hems with blind-stitching or topstitching. Serged-only hems on 'vintage' pieces date the construction firmly.
Frequently asked
Can a hem be re-done without losing value?
A like-for-like re-hem by a textile conservator (matching the original technique, thread, and length) does not significantly reduce value. A hem shortened by a later wearer using modern methods (machine topstitching or serging) reduces value substantially on quality pieces because the original length is gone and the construction language is broken.
How can I tell if a hem has been shortened?
Look for a horizontal crease line or colour change along the inside of the hem at the position of the original hem. Sun-bleaching, fold lines, and stitch holes from the original hem are usually visible even after the fabric is taken in. Compare the front and back lengths — a re-hemmed piece often has uneven front-to-back at the new hem.
