The UK decision is silk fibre versus a different, stretch-satin garment, not two equivalent silk sets. Silk Pyjamas Company declares mulberry silk at GBP 149; John Lewis's Sesame Jacquard Long Satin set declares polyester and elastane at GBP 45. The latter's care instructions are hand-wash-only despite its synthetic composition. Buyers should decide which fibre and laundry routine they want before comparing delivered costs.
Scope: Adult women's pyjama sets, with silk and non-silk alternatives identified separately. Children's sleepwear, baby accessories, medical suitability, safety certification and sleep-treatment claims are excluded.

Named options and evidence limits
Silk Pyjamas Company United Kingdom — women's mulberry silk set
The page lists GBP 149 including VAT for a top-and-trousers set, declared as 100% mulberry silk. It describes a notched collar, long sleeves and a drawstring waist. The selector lists Small and Large in Blue, Pink, Red and White. It advertises free UK delivery from GBP 75, with 24–48 hours handling before 5–7 days delivery.
Limitation: Composition and construction are seller declarations, not independent textile tests. Actual garment measurements, supplied care label, dispatch origin, return address and warranty conditions require confirmation. No skin, sleep, temperature-control, allergy or durability claim is endorsed. No available colour/size combination was confirmed. The seller's generic FAQ incorrectly equates satin with synthetic fibre; satin is a weave, not a fibre. Product-specific care and return conditions should be obtained.
John Lewis — Jacquard Long Satin Pyjama Set, Sesame, 28115029
The listing shows GBP 45, sizes 8–18, long sleeves and a button fastening. Composition is declared as 94% polyester and 6% elastane. Care states hand wash only, no bleach, no tumble drying, no ironing and no dry cleaning. The page describes unwanted-item returns within 30 days of receipt.
Limitation: This is not silk. Selected-size availability, postcode delivery and exact return eligibility were not checked. Environmental certification and sleep-related marketing are not evaluated or endorsed.
The John Lewis GBP 45 item sits below its published free standard-delivery threshold of over GBP 50; the page lists GBP 4.50 standard delivery otherwise. Collection is a separate option. Do not call the headline GBP 45 a universal delivered price or add products just to meet a threshold without comparing the final spend.
Checks before choosing
Read fibre content separately from the weave
Silk identifies a fibre; satin identifies a weave and can use silk or other fibres. See Museum of Fine Arts CAMEO: satin weave. A satin or silky product name does not establish silk content. Read the composition for the garment and any separate lace or trim. If genuine silk is essential, request the actual supplied label before ordering. Do not use sheen, photographs, a luxury name or price as proof of composition.
Match garment measurements, not size names
Ask for bust, hip, waist range, top length and inside-leg measurements for the selected size. Distinguish body measurements from finished-garment measurements and compare with a set that already fits. Small, Large and numbered sizes are not interchangeable across brands. For a two-piece set, check that both pieces work; an adjustable waist alone does not establish the fit of the shirt or trousers.
Check exactly what the price includes
Confirm whether the listing buys a shirt and trousers, a camisole and shorts, or just one separate. Do not treat a robe, mask, pouch or monogram in a photograph as included unless the description says so. Ask whether mixed top-and-bottom sizes are possible and whether a partial return is allowed. A gift set with accessories is not an equivalent unit to a plain two-piece set.
Choose a care and return routine you can use
Read this product's wash, drying and ironing directions before purchase. Polyester satin is not automatically machine washable, and silk is not automatically dry-clean-only: the named examples have different care instructions. Keep labels attached until you have checked the order and fit. Ask about returns after trying on, personalised items, sale exclusions, postage and deadlines. No repeated-wash or shrinkage test was performed.
Get an address-specific offer
Ask for a written total in GBP identifying the selected size, colour and included pieces. Record any separate shipping charge, tax or import-cost treatment, dispatch origin, return address and warranty exclusions. Missing details here are unverified, not a finding that a seller provides no warranty or returns. Where no current offer could be read, the source is explicitly an enquiry or catalogue reference, not a confirmed in-stock option.
Is polyester satin always the easier-care choice?
No. This John Lewis set specifies hand washing only and no tumble drying or ironing. Compare the actual labels rather than assuming a care routine from the fibre alone.
Methodology and limitations
We checked the publisher’s Silk Pyjamas Company country inventory, then primary retailer or specialist records relevant to United Kingdom. We used the approved non-ranking buying-guide format because complete product equivalence, selected-variant offers or specialist specifications were not sufficiently established. This selected-source guide is not an exhaustive market survey. Retailer claims are attributed and source-access limitations are visible; overseas prices are not ranked as local offers.
No hands-on testing, scoring, certification, safety assessment or performance ranking was performed. Testimonials and ratings are not findings. Item prices are dated observations, not guaranteed checkout totals. No cheapest-product, cooling, health, allergy-suitability or lifespan claim is made. We have not contacted sellers or submitted forms, orders or payments.
