Millie Blue: The Hand-Painted Hair Accessories Collectors Love

The Millie Blue signature clip, with its hand-painted forget-me-nots on a tortoiseshell base, remains one of the most sought-after finds at Portobello Road. Unlike many mass-produced mid-century accessories, each piece from this small British workshop carried a maker's mark—a tiny enameled bluebell—that collectors now hunt for with quiet determination. The brand operated from a single studio in South London between 1928 and 1958, producing combs, barrettes, and hair slides that blended Edwardian delicacy with Art Deco geometry.

Millie Blue products are defined by their distinctive palette: muted celadon, dusty rose, and a particular shade of lapis lazuli that the founder, Millicent Blumenthal, mixed herself using ground pigments and shellac. The technique—applying multiple thin layers of hand-mixed enamel over a stamped brass or silver-plated base—gave each piece a depth that machine-made rivals never achieved. The result is an accessory that looks different in morning light versus evening candlelight, a quality that made them popular with West End actresses in the 1930s.

The Materials That Defined Millie Blue

Understanding what makes Millie Blue products collectible starts with the materials. The workshop used three primary substrates:

• Sterling silver – reserved for limited-edition combs and hair pins, often hallmarked with the London assay office mark. These pieces are heavier and command higher prices today.
• Brass with silver plate – the most common base for clips and slides. The plating was thick enough to resist tarnishing for decades if cared for properly.
• Celluloid and early Bakelite – used for more affordable, everyday barrettes. Millie Blue’s celluloid pieces are notable for their marbled patterns, created by swirling two colours before the material set.

The enamels were all cold-applied and fired at low temperatures to avoid warping the metal. This made the colours vibrant but also meant the enamel could chip if dropped—a reason why mint-condition pieces are rare. The brand also experimented with inset semi-precious stones: amethyst chips, rose quartz, and freshwater seed pearls appear on some of the later 1940s designs.

Iconic Silhouettes and How to Spot Them

Three shapes dominate the Millie Blue catalogue. First, the “Bluebell” comb, a curved tortoiseshell comb with five graduated enamel blossoms along the top edge. Second, the “Cascade” barrette, a hinged clip with a waterfall of tiny enamel leaves in graduating sizes. Third, the “Dewdrop” slide, a flat, rectangular clip with a single large enamel droplet at the centre—often mistaken for a later 1960s design but actually introduced in 1935.

Genuine Millie Blue pieces always have the mark somewhere discreet: a tiny bluebell stamped into the metal, or an embossed “MB” on the reverse of the clip. The enamel work is smooth to the touch, never bumpy, and the colours are consistent across the piece. Faded or uneven colour often indicates a later reproduction or a piece that has been re-enamelled.

Styling Millie Blue with a Modern Wardrobe

The beauty of these accessories lies in their versatility. A single Dewdrop slide worn at the nape of the neck can anchor a low chignon for a formal dinner, while a Bluebell comb tucked into a half-up style adds a touch of whimsy to a linen sundress. Because the colours are muted rather than bright, they pair well with both neutral tones and bolder prints—try a lapis lazuli clip against a cream silk blouse or a dusty rose barrette with a navy tailored jacket.

For readers who love the layered look, stacking two Cascade barrettes on one side of a side part creates a contemporary effect that still honours the original design. The key is to let the accessory be the statement: keep the rest of the outfit simple, with clean lines and minimal jewellery. A Millie Blue comb also works beautifully as a brooch substitute—simply pin it to the lapel of a blazer using a small safety pin threaded through the back.

If you are new to collecting, start with the later 1940s pieces, which are more readily available and often in better condition than the 1930s silver examples. A good place to begin is the Caroline Turban Headband—though not a Millie Blue product, it shares the same era and styling sensibility, making it a natural companion in a vintage wardrobe. The Hot Pink Caroline Turban Headband: A Vintage Accessory with a Story shows how accessories from different makers can be mixed to create a cohesive look.

Care and Storage for Longevity

Millie Blue’s enamel is fragile, but with proper care these pieces can last another century. Avoid exposing them to water, perfume, hairspray, or direct sunlight for extended periods. After each wear, wipe the metal parts gently with a soft, dry cloth to remove oils from your skin. For silver pieces, use a silver polishing cloth only on the metal—never on the enamel. Store each piece separately in a fabric-lined box or a soft pouch; wrapping them in acid-free tissue paper prevents scratches between stacked items.

If a piece develops a light tarnish on the silver, a gentle rub with a jeweller’s cloth will restore the shine. Never use dipping solutions or ultrasonic cleaners, as they can loosen the enamel. For celluloid pieces, keep them away from heat and strong light, which can cause the material to yellow or warp. A cool, dark drawer is ideal.

Building a Collection: What to Look For

Because Millie Blue produced relatively small runs, no two pieces are exactly alike. The most valuable are the sterling silver combs with intact enamel and the rare “Cascade” barrettes that still have all their leaves—missing leaves are common. Prices at UK vintage fairs range from £25 for a common celluloid barrette to over £200 for a complete silver comb in its original box. Always check the hinge mechanism on hinged clips; a loose hinge can often be tightened by a jeweller, but a broken hinge is difficult to repair without damaging the enamel.

For those who enjoy the thrill of the hunt, keep an eye on the maker’s mark. Some later pieces (post-1950) were stamped with only “MB” in a rectangle, while earlier ones have the full bluebell shape. The bluebell mark is more desirable among serious collectors. Another tip: the backing plate on Millie Blue clips is usually stamped with a pattern number (e.g., “MB-47”), which can help date the piece. Pattern numbers starting with “MB-1” through “MB-30” are from the 1930s; “MB-31” to “MB-60” are 1940s; and higher numbers are 1950s.

If you come across a piece that appears to be Millie Blue but lacks any mark, examine the enamel work closely. The quality of the hand-painting is a giveaway: genuine pieces have tiny brush strokes visible under a magnifying glass, and the edges of the enamel are crisp, not blurred. A piece that looks too perfect, with machine-smooth enamel, is almost certainly a later reproduction.

Pairing Millie Blue with Other Vintage Accessories

One of the joys of collecting is learning how different makers complement each other. A Millie Blue clip can sit beautifully alongside a Conche Shell and Pearl Earrings set from the same period, creating a coherent but not matchy-matchy look. Conche Shell and Pearl Earrings: A Vintage Accessory Primer explains how to identify authentic shell pieces that share the same delicate aesthetic. Similarly, a Millie Blue comb worn with a simple velvet headband from the 1940s evokes the quiet elegance of wartime British fashion without feeling costumey.

For evening wear, try pairing a silver Millie Blue slide with a black velvet dress and pearl studs. The subtle shimmer of the enamel catches the light without competing with the pearls. In daytime, a celluloid marbled barrette tucked into a messy bun adds colour without looking overdone. The secret is restraint: let one Millie Blue piece be the focal point.

The Legacy of Millicent Blumenthal

Millicent Blumenthal trained as a miniature painter at the Royal College of Art before opening her workshop in 1928. She employed three assistants, all women, and insisted on hand-painting every enamel piece herself until the 1940s, when wartime shortages forced her to streamline production. After the war, she introduced the celluloid line to keep prices accessible, but the quality never dropped. The workshop closed in 1958 when Blumenthal retired, and no records of the patterns survived—which is why each piece discovered today feels like a small archaeological find.

Collectors often remark that Millie Blue accessories have a warmth that modern mass-produced items lack. That warmth comes from the human hand: the slight irregularity of a brush stroke, the deliberate choice of colour, the careful assembly of tiny parts. When you hold a Millie Blue clip, you are holding a piece of someone’s life’s work—and that is worth preserving.

When storing your collection, wrap each clip in acid-free tissue paper to prevent scratching the enamel. A small silica gel packet in the storage box will absorb moisture without damaging the materials. Check your pieces once a year for any signs of enamel lifting or metal fatigue, and consult a professional conservator if you notice damage. With mindful care, these delicate treasures will continue to bring joy for generations to come.
