How to Measure Yourself
Use a flexible measuring tape and wear lightweight clothing for the most accurate body measurements.
Bust
Measure around the fullest part of your bust while keeping the measuring tape straight and level across your back. Keep the tape comfortably fitted without pulling it too tightly.
Waist
Measure around the narrowest part of your natural waist. This is normally located above the belly button and below the rib cage.
Hips
Stand with your feet together and measure around the fullest part of your hips and seat while keeping the measuring tape level.
Understanding Different Lengths
Sleepwear length may appear differently depending on your height, body proportions, and the individual product design.
Short Pajama Sets
Short pajama sets generally include a relaxed top with matching shorts. The shorts may sit at the upper or mid-thigh depending on your height and body proportions.
Cropped Sleepwear
Capri or cropped pajama trousers generally finish below the knee or around the lower calf, offering a lightweight and comfortable fit.
Full-Length Pajamas
Full-length pajama trousers are designed to extend toward the ankle. The exact position may vary depending on your height and the trouser cut.
What to Keep in Mind
Designed to provide relaxed comfort for a variety of body shapes.
Created for comfortable sleeping, lounging, and easy movement.
Some styles include stretch, elastic, drawstring, or adjustable details.
Trouser, short, sleeve, and top lengths may vary according to height.
Relaxed, fitted, oversized, and flowy styles may fit differently.
Fabric composition, stretch, thickness, and structure vary by style.
How Different Styles May Fit
Each sleepwear style creates a different feel and may fit the body in a slightly different way.
Relaxed Pajama Sets
Designed with additional room through the bust, waist, hips, and legs to provide comfortable movement while sleeping or lounging.
Fitted Sleepwear
Designed to sit closer to the body. Fabric stretch and material composition can significantly affect the overall fit.
Oversized Loungewear
Designed with a deliberately loose silhouette for extra room, relaxed comfort, and an effortless lounge-inspired appearance.
Adjustable Styles
May include shoulder straps, drawstrings, elasticated sections, tie waists, or flexible closures that help personalize the fit.
How Material Affects Fit
Material composition can influence how sleepwear feels, stretches, drapes, and moves against the body.
Stretch Fabric
Stretch fabrics can adapt more easily to the body and may provide greater flexibility through the bust, waist, and hips.
Satin-Feel Fabric
Satin-feel materials generally provide a smooth and fluid drape but may offer less stretch than jersey or elastane-blend fabrics.
Lightweight Fabric
Lightweight fabrics can feel breathable and soft, although lighter colours may appear slightly more sheer under bright lighting.
Elasticated Details
Elasticated waistbands, cuffs, or panels may provide additional flexibility and help the garment adapt comfortably to the body.
Review the Individual Product Details
Although many Belluirea sleepwear styles are available in One Size, each design may differ in stretch, structure, trouser length, sleeve length, neckline, waistband, fabric, and overall silhouette.
Always review the individual product description, available measurements, material information, and product images before placing your order.
Compare your body measurements with the size guide.
Check whether the material is stretchy or non-stretch.
Review the top, sleeve, short, and trouser lengths.
Read the product-specific fit description carefully.
This size guide provides general recommendations only. Fit may vary depending on the fabric, stretch, cut, neckline, sleeve design, waistband, trouser length, and overall silhouette of each sleepwear product. Please allow a possible measurement difference of approximately 1–3 cm due to manual measuring and the production process.
