Men's pajamas should leave room to sit, bend and rest without the shirt pulling at the buttons or the waistband digging in. A good starting point is your current chest and waist measurement, followed by the size chart for the exact set. Your usual T-shirt size is not a reliable substitute.
The other useful point is simple: a matching shirt and pair of trousers do not always need the same size label. This guide uses the Garnet Scroll Luxury Organic Cotton Sateen Pajama Set, where you choose the two sizes independently.
Measure your body, not a shirt laid on a table
Use a flexible measuring tape, stand naturally and avoid holding your breath or pulling the tape tight. Keep the tape level all the way around. If possible, ask someone to check that it is not riding up at the back.
- Chest: measure around the fullest part of your chest, under your arms. Let your arms rest naturally when taking the reading.
- Natural waist: measure around your natural waist with the tape resting against your body. Do not use the size printed inside a pair of jeans as the measurement.
- Record both figures: use the same unit as the size chart. Take each measurement again if the tape has shifted.
Garnet Scroll's supplier chart gives body measurements, not finished garment measurements. Do not double the width of an existing garment and treat that as your body measurement. The chart also does not provide an inseam or a finished shirt length, so those cannot be inferred from the size label.
Garnet Scroll body-size chart
Use the chest and waist ranges when considering the shirt, and the waist range for the trousers. The available size range is 2XS–7XL. These figures apply to this set's supplier guide; other UNIKCOSA garment types can use different charts.
| Size | Chest (cm) | Waist (cm) |
|---|---|---|
| 2XS | 88–91 | 69–72 |
| XS | 92–95 | 73–76 |
| S | 96–99 | 77–80 |
| M | 100–103 | 81–84 |
| L | 104–107 | 85–88 |
| XL | 108–111 | 89–92 |
| 2XL | 112–115 | 93–96 |
| 3XL | 116–119 | 97–100 |
| 4XL | 120–123 | 101–104 |
| 5XL | 124–129 | 105–110 |
| 6XL | 130–135 | 111–116 |
| 7XL | 136–141 | 117–122 |
For the supplier's inch ranges, use the full table on the product page. If your measurement falls between listed ranges, or your chest and waist indicate conflicting shirt sizes, contact UNIKCOSA before ordering rather than guessing.
How to select different sizes for the two pieces
Suppose your chest is 105 cm and your natural waist is 82 cm. The chest measurement falls within the guide's L range, while the waist falls within M. This is a reason to consider a larger shirt and smaller trousers, then check whether the shirt's proportions suit you; it is not a promise of an exact fit.
On the product page, choose Shirt size and Trouser size separately. Check both selections again before adding the set to your bag. One $399 set contains one shirt and one pair of trousers, even when the size labels differ.
The trouser drawstring adjusts the waist fastening. It does not change the seat, rise or leg length, and it cannot make an undersized pair of trousers comfortable. Avoid choosing an unsuitable size simply because the waist can be tied.
What a comfortable pajama fit should look like
The shirt
The button front should lie comfortably while you stand and sit. Persistent pulling between buttons is a sign to reassess the fit. Raise your arms and reach forward gently: the upper back and sleeves should allow your normal movements without strain. The collar should rest comfortably, and cuffs should not interfere with your hands.
The trousers
The waistband should feel secure without needing an excessively tight knot. Check comfort at the seat and upper thighs when sitting. The hems should not create a trip hazard. If you need a specific inseam or length, ask for guidance before ordering; height alone does not tell you how a particular pair will fit.
The complete set
For nightwear, judge the outfit in a natural, relaxed posture. A styled image can help you picture the design, but it cannot tell you how that size will fit your body. Garnet Scroll includes original supplier garment views alongside an AI-generated model styling illustration.
Before you place the order
- Recheck your chest and waist measurements.
- Confirm both size selectors, rather than leaving one at its default.
- Read the shipping policy and return policy.
- Ask about any measurement that the chart does not provide.
- Choose the fabric as carefully as the size. Our cotton sateen versus silk guide explains the distinction.
Common fit questions
Should I automatically size up in pajamas?
No. Start with the actual product chart and your measurements. Automatically sizing up can create excessive sleeve or leg length without solving the fit issue you are concerned about.
Can I select L for the shirt and M for the trousers?
Yes. Garnet Scroll has separate shirt and trouser selectors. Select each piece using the relevant measurements and confirm the choices in your bag.
Does this chart apply to every UNIKCOSA product?
No. It is the supplier body-size guide for this pajama set. Always read the chart on the specific product you are buying.
