Size Guide
Lunya Size Guide
Body measurements for women’s sleepwear and loungewear, bralettes, men’s sleepwear and robes. All measurements refer to body size, not garment size, unless a length column says otherwise.
Women’s Sleepwear & Loungewear
The core chart for pajama sets, sleep tees, tanks, joggers, henleys and everyday loungewear. Many styles are labelled with a dual size such as XS/S or L/XL — use the matching row in the Lunya Size column.

Sleep shorts run to an inseam of about 2 in across the range, with the rise stepping from 11 in to 15.5 in as the size grows.
Select Washable Silk Styles — Extended Ladder
Some washable silk sets use this six-step ladder instead of the XS–XL chart above. Check the size options shown on the style you are buying: if you see XL2 or XL3, use this table.

Men’s knit shorts carry a 7.5 in inseam. Measurements are in inches and refer to body size unless otherwise noted.
How to Measure
Use a soft tape over bare skin or thin undergarments. Keep the tape horizontal and comfortably loose — never pull it tight.
-
Bust or chest
Wrap the tape under your arms and around the fullest part of your chest, keeping the tape level all the way around.
-
Natural waist
Bend side to side to find the crease at your natural waist, then measure around that point with the tape comfortably loose.
-
Hip
Stand with your feet shoulder-width apart and measure around the fullest part of your hips and seat.
-
Match the numbers
If your bust and waist point to two different sizes, order the size indicated by your bust measurement.
Getting the Fit Right
Between two sizes
Order the smaller size for a closer fit or the larger size for a looser one. On rigid woven silk, sizing up is the safer call.
Oversized by design
Many tees, henleys and robes are cut with a dropped shoulder and generous ease. Take your usual size, or size down one step for less volume.
Fabric changes the fit
Washable silk and cotton silk are woven, so they relax very little. Pima cotton and modal knits carry functional stretch and give a little with wear.
Check the length
Robe length runs 57 to 61 in, sleep dresses 39 to 40.5 in, and pant inseam 29 to 31 in. Compare those numbers with your height before you choose.
Dual sizes are normal
A style labelled XS/S fits the 0–4 range, M covers 6–8, and L/XL covers 10–14. Two inch steps in the chest separate each block.
One-size accessories
Sleep masks, scrunchies, travel pouches and gift packaging come in one size, so no measuring is needed for those pieces.
