The p404 Julia Alpaca Jumper: Vintage British Knitwear with a Quiet Following

Among the many numbered codes that collectors encounter in British vintage fashion, the p404 Julia Alpaca Jumper has a quiet but devoted following. Unlike the more widely discussed p158 Julia Alpaca Jumper, which often appears in cream and charcoal, the p404 is distinguished by its slightly heavier weight, a subtle cable panel along the sleeves, and a label that reads ‘Julia – Made in England – 404’. This jumper rarely surfaces in charity shops or online listings, and when it does, the alpaca content – usually 60–70% baby alpaca blended with lambswool – is the first detail that seasoned buyers check.

What Makes the p404 Special?

Alpaca wool has been prized in British knitwear since the 1950s for its warmth without weight. The p404 Julia uses a two-ply yarn that creates a soft halo, similar to mohair but less prone to pilling. The cut is a classic crew neck with slightly dropped shoulders, typical of late-1960s and early-1970s British casual knits. The main difference from the p158 is the sleeve detail: a narrow cable that runs from the shoulder seam to the cuff, giving it a dressier feel. The colour palette of the p404 also leans towards muted tones – heather grey, oatmeal, and a dusty rose that collectors call ‘Julia pink’.

Another identifier is the internal care tag. While the p158 often has a simple woven label, the p404 includes a printed tag with washing instructions in English and French, plus the code ‘404’ stamped in black ink. This suggests it was produced in a later batch, possibly for a small boutique chain rather than department stores. The jumper’s construction – fully fashioned with hand-finished seams – indicates it was made in a Midlands factory that specialised in luxury knitwear for the export market.

Styling the p404 with Vintage Hair Accessories

The Julia Alpaca Jumper’s soft texture and neutral colours make it an ideal canvas for vintage hair accessories. A cream or heather grey p404 pairs beautifully with a velvet headband in burgundy or forest green – the contrast of textures between the napped alpaca and smooth velvet creates a balanced look. For readers who own the Decoding the Store P160 Faux Pearl Hair Clip: A Collector’s Guide, the delicate lustre of faux pearls against the matte alpaca is a combination that appears in many 1960s fashion spreads.

If you prefer a more understated accessory, consider a French barrette in tortoiseshell or dark horn. The p404’s crew neck leaves the collarbone area exposed, so a barrette worn at the nape of the neck or securing a low twist adds a touch of structure without competing with the jumper’s softness. For evening wear, a vintage gold-toned hair comb tucked into a chignon echoes the subtle cable detail on the sleeves. The key is to let the jumper’s alpaca texture remain the hero, using hair accessories as quiet accents.

Those who already have the p158 Julia Alpaca Jumper might wonder how the p404 differs in everyday wear. The p158 is slightly lighter and more casual, ideal for layering under a blazer. The p404, with its cable detail and denser knit, works better as a standalone piece. When styling both with hair accessories, the p158 suits playful clips – like the Boone Cocktail Ring Clip – while the p404 calls for more refined pieces such as a velvet twist headband or a pearl-studded slide.

Caring for Your p404 Julia Alpaca Jumper

Alpaca wool is naturally resilient, but it requires gentle handling to maintain its halo and shape. Here are the steps I follow for my own p404:

• Hand wash only – use lukewarm water (no hotter than 30°C) and a wool-specific detergent. Never agitate or wring; instead, submerge and press the jumper gently.
• Rinse thoroughly – two or three changes of water at the same temperature, then press out excess moisture by rolling the jumper in a clean towel.
• Dry flat – reshape the jumper on a drying rack or a dry towel away from direct sunlight and radiators. Never hang it, as the weight of the wet wool can stretch the shoulders.
• Store folded – avoid hangers. Fold the jumper with acid-free tissue paper to prevent creases. Moth protection is essential: cedar blocks or lavender sachets work well without the chemical smell of naphthalene.

If your p404 develops bobbles, use a fine sweater comb or a fabric shaver with a gentle setting – the alpaca fibres are delicate, and aggressive shaving can create bald patches. For minor pulls, a crochet hook can draw the loose thread to the inside of the garment.

Identifying Authentic p404 Jumpers

Because the p404 is less common than the p158, fakes are rare, but mislabelling happens. Check three things: the label must say ‘Julia’ and ‘404’ (the number is always three digits, stamped not embroidered); the seam allowance inside the sleeve should be finished with a zigzag stitch in a matching colour; and the alpaca content should be listed as a percentage on the care tag. If the jumper feels too silky or lacks the characteristic halo, it may be a modern acrylic blend passed off as vintage.

Where to Look for the p404

British vintage fairs, especially those in the Midlands and the Home Counties, sometimes yield a p404. Online platforms such as eBay and Etsy can be searched using the terms ‘Julia alpaca jumper 404’ or ‘vintage British knitwear 404’. Be patient – the jumper often appears under vague titles like ‘vintage cream jumper’ because sellers don’t recognise the code. When you find one, check the measurements carefully: the p404 was produced in sizes 10 to 14 (UK) and tends to fit true to size, though the alpaca yarn can relax slightly over time. A bust measurement of 36 inches (91 cm) is typical for a size 12.

If you already own the p158 and are considering adding the p404 to your wardrobe, remember that the two jumpers are complementary rather than identical. The p404 fills a different niche: slightly dressier, slightly warmer, and with a colour range that includes the dusty rose that the p158 never offered. Together, they form a capsule collection of British alpaca knitwear that spans the late 1960s to early 1970s.

One final practical note: when you receive a p404, give it a gentle steam (from a handheld steamer held at least 15 cm away) to revive the fibres before the first wear. This helps the alpaca regain its natural loft and removes any storage odours without the need for washing. Then clip on a tortoiseshell barrette or a pearl slide, and that dusty rose p404 becomes a direct line to 1960s British design — no fuss, just good knitwear.
