The pajamas look beautiful on the model. Then you open the size chart, see a momme number, and realize you still don’t know whether the waistband will bother you when you sit down—or whether you’ll ever get around to hand-washing them.
At THXSILK, our advice is to start with how you’ll wear them: sleeping, lounging, or both. Check the fiber content, fit information, and care instructions first. Once those work for you, compare fabric weight, coverage, details, and price. We wouldn’t steer you toward the highest momme number just because it’s higher.
Silk’s smooth, soft feel can be a lovely reason to choose it. Let’s find the garment details that make sense for your everyday routine, too.
Start With What You Want to Change
Think about the pajamas you reach for—and the pair you leave in the drawer. We’d use what separates them to decide where to start looking.
If a waistband digs in during breakfast, put waistband construction first. If sleeves cover your hands, ask for sleeve measurements. If turning over feels restrictive, examine the cut through the shoulders, chest, hips, and thighs. If special laundry keeps a favorite pair out of rotation, check care before considering another one.
Match the change to the problem: heavier fabric won’t answer a question about sleeve length.
For sleeping, start with the coverage and freedom of movement you already prefer. For lounging, you might put pockets, a button-front top, or longer sleeves higher on your list. Want one set for both? We’d give your bedtime needs priority; a pair that looks right on the couch but bothers you in bed misses half its job.
Check the Fabric, Not Just the Word “Silky”
Suppose you’re comparing pajamas described as “silky satin” with a pair advertised as “100% mulberry silk.” Our first advice is to open the fiber-content details for both—not choose by the headline or the shine in a photo.
Look for the actual fiber names and percentages. If pure silk is what you want, check that the fabric’s composition states 100% silk. For a blend, check how much silk it contains and which other fibers are listed. Read any separate descriptions of the main fabric, lining, or trims; don’t assume every part has the same composition. The FTC’s textile-labeling guidance explains why the fiber-content label matters.
On a label, those terms answer different questions:
- Silk is the fiber. Look for its percentage, not just a silky-feel description.
- Mulberry silk identifies the silk source; the word alone doesn’t tell you the finished fabric’s silk percentage or the garment’s construction.
- Satin is a weave, not a fiber name. Check what fibers make up that satin before treating it as a silk option.
If the description stops at “silky,” “premium,” or “mulberry” and leaves the composition unclear, ask for the fiber-content information before ordering. A pure-silk label tells you what you’re choosing, not that it will feel better to you than every alternative.
For a relaxed, flowing look, we’d also check the cut and any movement photos or video. Silk is valued for its smooth feel and fluid drape, but weave, weight, and garment construction affect how a particular pair hangs. Choose useful fabric and garment details over an unexplained “best silk” label.
Get the Fit Right Beyond the Size Letter
When using our size charts, start by checking what is being measured. Body measurements describe the person a size is intended to fit. Garment measurements describe the clothes themselves—not the body-size range they will fit.
For a garment chart, compare with a comfortable pair you own, using the same method. Check whether the figures are full circumferences or flat widths, and look for the intended fit and room to move. If a measurement isn’t explained, confirm it before choosing a size.
Same “S,” Different Information
Our 19 Momme Classic Mulberry Silk Pajama Set lists women’s size S with a 39-inch bust and a 28–32-inch waist. Our 22 Momme Premium Mulberry Silk Pajama Set with Gift Box also lists a 39-inch bust, but its S waist is shown as 32 inches.
Both charts use garment measurements, not body-size ranges. Our charts show a waist range for one set and a single measurement for the other, without explaining how each was taken. We recommend confirming the measurement method before comparing their fit. The figures don’t establish equal fit or which set is looser, and these women’s examples aren’t men’s sizing guidance.
Check the Part That Usually Bothers You
- Waistband: Check for elastic, a drawstring, or both. If pressure bothers you, ask about the relaxed waist measurement and construction; a drawstring alone doesn’t tell you how it will feel.
- Chest and hips: Prioritize room where you usually feel pulling. If your top and bottom need different sizes, check whether separates are available.
- Length: Check sleeves and pant length separately from width. For longer limbs, we’d ask for an inseam or sleeve measurement rather than simply choose a larger size.
- Details against your body: Check buttons, seams, and labels. If hard buttons bother you when lying down, consider a pull-on style.

When trying on a pair within the stated return conditions, sit down, reach forward, and bend your knees. Notice pulling, digging, or cuffs getting in the way—not just how the pajamas look while you stand.
Match Coverage and Fabric Weight to Your Routine
Choose the coverage you already enjoy before comparing fabric weights. If you normally sleep in a short top and shorts, start there rather than buying a long set solely because it is labeled lightweight. If you like covered legs while lounging, long pants may matter more than a small difference in weight.
Momme measures silk fabric weight; it is not a complete quality score. Carnegie Mellon’s textile guide describes the measure.
Between otherwise suitable options, we’d recommend starting with 19 momme if you want a lighter fabric weight; compare 22 if you prefer more substance. Don’t use the number alone to decide softness, drape, opacity, or how long the pajamas will last. Ask for relevant fabric details or photos when one of those matters to you.
For warmer conditions, some sleepers prefer silk’s smooth, lightweight feel. Think about your usual bedroom, bedding, coverage, and personal preference together—not a fixed “summer momme” or “winter momme.” A warm bedroom in January may call for a different choice from a strongly air-conditioned room in July.
Read the Care Instructions Before You Commit
Before you put a set on your shortlist, we’d check how it will fit into laundry day. “Washable” isn’t enough: read the washing and drying instructions for that garment. Machine washing, hand washing, and tumble drying are separate permissions; don’t assume one from another.
For both sets, we recommend hand washing in cold water. Their care instructions also allow a gentle or silk machine cycle when needed, but not tumble drying. If you’re happy to use a gentle wash and air-dry your pajamas, that routine may work for you. If everything needs to go through a regular wash-and-dry cycle, we wouldn’t recommend these two sets for that routine.
Check the required detergent and whether you have somewhere suitable to dry the garment. Follow the attached care label if it differs from general advice. Choose care you’ll actually manage, not a routine you hope you’ll adopt after buying.
Build a Shortlist That Works Within Your Budget
Set your spending limit, then separate the essentials from the extras:
- Must-have: Your required fiber content, enough fit information to select a size, a suitable cut, and care you can manage.
- Preference: Fabric weight, color, piping, pockets, or a particular style of collar—unless one of these is essential to your intended use.
- Need to verify: An unexplained waistband measurement, missing inseam, unclear fabric composition, or incomplete drying instructions. Ask rather than filling in the gap yourself.
We’d spend extra on a feature you expect to use, after the must-haves are met. If two sets both fit your requirements but only one has the pocket you want for lounging, that is a concrete reason to prefer it. If the main difference is a higher momme number and you want a lighter fabric, paying more for weight is not an upgrade for your needs.
Before ordering, check the current return conditions, including any try-on restrictions, and make sure the chosen size and color are available. Don’t assume a policy or stock status from another item.
Choose the pair you can picture wearing through an ordinary evening, night, and laundry day. If one important fit question is still unanswered, our advice is to get that answer first—not guess your way to checkout.
