Maternity and Baby Knitwear Manufacturing: Two Size Systems, One Programme

Maternity and baby knitwear look like one line on a range plan and behave like two programmes. They share a customer and a shelf, and almost nothing else: two size systems, two fibre standards, and two completely different definitions of what "fits" means.

This is a count of our own published range: 18 styles live on lcsweater.com right now — 12 maternity graded XS–XL and 6 baby graded 0–24m. Every figure below comes from that count.

Our MOQ is 30 pieces per colour, and it applies to each size system separately — a maternity cardigan and a matching baby cardigan are two styles, not one.

That is worth stating early because the matching mother-and-baby set is the thing brands most often want and most often under-budget. It is an attractive product and it is two garments.

Counted across the 18 published styles: cotton in 11, bamboo in 4, wool in 4, merino in 3, cashmere in 2, plus modal, spandex and recycled polyester on individual pieces.

Cotton or bamboo appears on 12 of the 18 styles — cotton on 11, bamboo on 4. For baby product that is not a preference, it is the entry requirement — and for maternity it matters almost as much, because skin sensitivity changes during pregnancy and a yarn that was fine before can stop being fine.

Specific choices in the published range worth copying:

• 100% organic cotton on the baby textured cardigan and on two maternity pieces
• Bamboo viscose blends where drape matters — the baby romper, the lightweight maternity pullover
• Merino rather than coarse wool where warmth is needed next to skin — the baby hooded sweater is 100% merino for exactly this reason
• Modal with spandex on the seamless maternity top, where recovery over a changing body is the whole product

Wool that itches is a returns problem in any category. In this one it is a returns problem plus a review problem.

Seven of our 12 published maternity styles carry nursing access. Five are named as nursing pieces — a cable-knit nursing cardigan, a colourblock nursing hoodie, a Fair Isle nursing sweater, a turtleneck with a hidden zipper and a wrap-style nursing sweater — and two more provide it by construction: a side-zip merino pullover and a wrap cardigan.

Every one of those solves the same problem differently — wrap, hidden zip, side zip, button placket — and the choice changes the panel shaping. It has to be on the tech pack before knitting starts, not added at fit sampling.

Two things that go wrong when it is left late:

• A zip added to a knitted panel after the fact will ripple. The band has to be knitted to a stable width and tension for the closure it is going to carry. This is the same failure mode as a cardigan front band, and it is more visible here because the opening sits across the bust.
• A wrap that works flat does not always work on a changing body. Wrap and tie positions need a fit sample on a real body at more than one stage, not a flat measurement check.

The garment has to work across a body that changes for months, and then often has to work again afterwards. In the published range that is handled three ways: high-low hems, side ruching and side seams that release, and wrap or tie constructions that adjust.

What does not work is grading a standard women's block up a size and calling it maternity. The change is not uniform — bust, waist and hip do not move together — and a straight grade produces a garment that is tight where it matters and loose everywhere else.

11 of the 18 styles carry a published index figure; the other 7 are quoted individually.

By product type, at MOQ 30 per colour, FOB:

By yarn family, on the styles that carry one: cotton blend USD 14.98, wool blend USD 17.36, 100% merino USD 44.27, cashmere on a cotton base USD 45.77, cashmere on a wool base USD 66.05.

Two readings that matter for planning:

A set costs like two garments because it is two garments. The knit bottoms and sets median is USD 40.03 — nearly double a pullover. It reads as one line on a range plan and arrives as two on the invoice.

The organic-cotton and bamboo core sits near the bottom of the fibre ladder. Cotton blend at USD 14.98 is the cheapest position in the whole catalogue apart from plain cotton, which means the fibre choice this category actually requires is also its most affordable one. The cost pressure here is construction — nursing openings, seamless knitting, fine gauge — not yarn.

11 of 18 sit at 7GG–12GG, which is the band that works for both wearers — warm enough for a baby layer, light enough for a maternity piece worn indoors through a long pregnancy. The two fine-gauge styles are the seamless maternity top and the baby romper, both next-to-skin pieces.

If you are building this line, decide the nursing access and the size systems before anything else — those two are what the tech pack is really about. Browse the published range, request a quote, or send a photo of the reference piece on WhatsApp.
