Comparison: Quick Verdict
I would choose Blissy when its 22-momme mulberry-silk case, zip closure and selected size match the pillow and price you want. LILYSILK is worth comparing when you want a different fabric weight, closure or coordinated bedding range. Compare the exact products: LILYSILK is not limited to one 19-momme case, and silk weight alone does not establish the better pillowcase.
The sensible reason to buy either is the feel and construction of the case you will use and wash. A smoother surface can be more comfortable than a rougher fabric, but a pillowcase is not a treatment for acne, hair loss, wrinkles or a sleep condition. I would not pay a large premium on the strength of those promises.
Compare the selected pillowcases
| Buying detail | Blissy | LILYSILK |
|---|---|---|
| Fabric to verify | The selected mulberry-silk product and composition label | The exact product’s composition; the range includes different silk options |
| Momme | Blissy commonly specifies 22 momme | Varies by product; do not assume every case is 19 momme |
| Closure and dimensions | Check the selected size and zip arrangement | Check the selected envelope or zip design and actual dimensions |
| Main attraction | A straightforward silk-pillowcase purchase when its finish and fit suit you | A broader choice of weights, designs and matching bedding |
| Ownership check | Care label, colourfastness precautions and seller terms | The same checks, especially when comparing a different weave or weight |
Momme describes silk fabric weight, not thread count. A higher number usually means more silk mass per area, but sewing, weave, finishing and care affect how a case wears. It is not a clinical rating, a thread-count equivalent or a guarantee that one brand outlasts another.
Blissy: what I like and what I would check

I like the smooth feel and the contained finish of a well-fitting zip case. A closure that keeps the pillow inside can be useful if you move around in bed, but only when the pillow fits without straining the seam or zip. Check centimetres or inches against the actual pillow; ‘queen’ or ‘standard’ names are not universally identical.
Our existing Blissy assessment described a comfortable, cool-feeling surface during use. That is a qualitative impression, not a temperature measurement or a promise of all-night cooling. Room temperature, bedding, pillow filling and the sleeper all affect comfort. Silk does not actively refrigerate a pillow.
The limitations are care and cost. A pale case can show oils or cosmetics; a coloured one needs the washing precautions on its label. Delicate fabric can snag on rough nails, jewellery or an exposed fastener. A strong closure does not make the fabric immune to damage.
LILYSILK: choose the product rather than the brand-wide label

LILYSILK makes sense when you want to compare weights, finishes or bedding combinations. Check whether the product you have selected has the same dimensions, closure and fabric composition as the Blissy offer. Otherwise you can mistake the price difference between two products for a quality difference between two entire brands.
I would not reject a properly made 19-momme case solely because it is lighter than a 22-momme one. A lighter fabric may suit your preference and budget. Nor would I automatically pay more for a heavier case without considering construction, laundering and the total cost of a usable pair.
Look closely at the opening and seams. An envelope closure can be comfortable without a zip near the face, but its overlap and fit need to retain the pillow. A zip case needs a smooth, covered fastening and enough room for the filling. Neither design is categorically better.
Silk, satin and certification are different questions
Silk is a fibre; satin describes a weave. A silk pillowcase can have a satin weave, and a satin case can instead be made from polyester or another fibre. The useful comparison is the actual composition and construction, not a blanket claim that silk and satin are opposites.
If a selected item carries an OEKO-TEX label, read the certification at the product’s actual scope. A tested-substance certification does not prove medical benefit, sustainable production in every respect, or superior comfort for your particular skin. Do not confuse it with organic certification or a durability score.
Care and value over a year
- Use the exact care label, an appropriate gentle detergent and the permitted water temperature.
- Protect a machine-washable case in a suitable laundry bag when the label recommends it; keep it away from abrasive garments and zips.
- Avoid bleach, unapproved high heat and aggressive wringing.
- Allow for drying and rotation: a second case can matter more than an optional accessory.
- Inspect seams and the closure after washing; address a snag gently rather than pulling a loose thread.
Compare delivered prices for the same size, number of cases and material, including any applicable shipping and taxes. Check whether the selected colour or personalised item has different return conditions. A headline discount or an old ’60-day guarantee’ in a review does not establish the conditions of today’s order.
My verdict and alternatives
Blissy is my straightforward choice when its 22-momme zip case fits your pillow and budget. LILYSILK can be the better purchase when a particular weight or closure suits you more closely. The decision should rest on a matched product comparison and realistic care, not a supposed universal benefit of a higher momme number.
A well-made cotton case remains a practical alternative if frequent hot washing, low cost or easy replacement matters most. Polyester satin can offer a smooth surface for less money, but it has a different fibre composition. For another silk comparison, see ZIMASILK versus Blissy.

Frequently asked questions
What is charmeuse silk?
Charmeuse is a fabric construction with a smooth, lustrous face and a different reverse. Check the fibre composition as well as the weave; a satin-like finish alone does not establish pure silk.
Does higher momme mean higher thread count?
No. Momme is a fabric-weight measure. A heavier silk case can feel more substantial, but weave, seams, finishing and care also affect ownership.
Are there alternatives to Blissy and LILYSILK?
Yes. Compare other accurately labelled silk cases, cotton cases or synthetic satin according to your budget, feel and washing needs. Match dimensions and construction rather than assume a brand is automatically better.
Is LILYSILK always 19 momme?
No. The brand offers different products. Read the selected case’s composition, weight, closure and dimensions instead of applying one older specification to the entire range.
Is a Blissy pillowcase good value?
It can be if the fabric feel, fit, closure and price suit you and you can follow its care label. I would not justify the premium with a promise to treat skin, hair or sleep problems.
Is Blissy silk or satin?
These terms answer different questions. Silk identifies the fibre; satin identifies a weave. Confirm the selected product’s composition label.
What matters most when buying a silk pillowcase?
Match the actual pillow dimensions, fibre composition, momme, closure, care instructions and complete price. Read the current seller’s returns conditions before use or washing.
