Choosing a nightwear size should be the easiest part of the purchase, and it is routinely the part people get wrong. Sleepwear is cut looser than daywear, so the size you wear in jeans or a kurti is not a reliable guide, and the number on the label means different things across categories.
The result is predictable. A set arrives, the top fits and the bottoms do not, and the parcel goes back. Almost all of it is avoidable with two measurements and five minutes.
This guide covers how to measure yourself properly, how to read a nightwear size chart, what "free size" genuinely means, and what to do when you fall between sizes. The size availability figures throughout are taken from the current Ecstasy range, so they reflect real stock rather than generic advice.
Measure your bust and your hip, then choose your size from whichever is larger. For two-piece sets the hip is usually the deciding measurement, because the lower half has less built-in ease than the top. Do not size up as a precaution — sleepwear already includes relaxed ease.

Key Takeaways
- Measure bust and hip. Size to the larger of the two.
- On a two-piece set, the lower half is the limiting piece — not the top.
- Sleepwear is already cut loose. Sizing up creates a garment that slips, not one that fits.
- "Free size" is not a universal size. It usually corresponds to roughly M to L.
- Graded sizes above XL are far more common in cotton sets than in occasion pieces.
Why Sleepwear Sizing Works Differently
Daywear is cut to sit close to the body, so its sizing is relatively precise. Sleepwear is cut with deliberate ease — extra room designed in so the garment does not restrict you while you move or sleep. That ease is why a size M nightwear top can feel considerably roomier than a size M shirt.
This causes two opposite errors. Some people size up because sleepwear "should be loose", and end up with a shoulder seam halfway down the arm and a waistband that will not stay put. Others size down because the garment looks generous on the model, then find it pulls across the hip when they sit.
The reliable approach ignores how the garment looks and works from your own measurements against the specific chart for that product. Charts differ between brands and even between styles, which is why "I'm usually a large" is not information a size chart can use.
How Size Ranges Have Widened
Indian nightwear was sold almost entirely in free size for a long time, which worked for the retailer and poorly for everyone else. That has changed at the daily-wear end of the market, where graded sizing is now standard and extended sizes are expected rather than exceptional.
The shift has been uneven, though, and it is worth knowing where it has and has not happened. Cotton daily-wear sets now routinely carry graded sizes through 2XL and sometimes 3XL. Occasion categories — babydolls, bridal pieces — remain predominantly free size, because they are cut loose and bought for single events.
Our own range reflects that split precisely, and we would rather set it out plainly than let you discover it at checkout.
Quick Answers Before You Measure
Should you buy nightwear a size bigger?
No. Sleepwear already includes relaxed ease. Buying a size up usually produces a dropped shoulder and a lower half that slides down, which is less comfortable than the correct size, not more.
What does free size mean in nightwear?
It means one size cut generously enough to fit a range of bodies, typically corresponding to roughly M to L. It is not a universal size, and it will not fit everyone.
Is 2XL the same as XXL?
Yes. They are two ways of writing the same size. Indian retailers use both, sometimes on the same site, which causes unnecessary confusion.
Taking Your Measurements in Six Steps
- Use a soft measuring tape, not a ruler or a piece of string held against one.
- Measure over light clothing or bare skin, never over a thick layer.
- Bust: run the tape around the fullest part, keeping it level all the way round and parallel to the floor.
- Hip: measure the fullest part, usually seven to nine inches below the waist. Keep your feet together.
- Waist: measure at the narrowest point, useful for drawstring styles.
- Keep the tape snug, not tight. You should be able to slide one finger underneath it comfortably.
Write the numbers down and use them against the chart on the product page. Do not adjust them upward "for comfort" — the garment's cut already does that.
Which Measurement Decides Your Size
| Garment | Deciding Measurement | Why |
|---|---|---|
| Two-piece set | Hip | The lower half has less ease than the top |
| One-piece nighty | Bust | The garment falls from the shoulders |
| Babydoll | Bust | Fitted at the bust, loose below |
| Co-ord set | Hip | Cut closer than sleepwear sets |
| Bridal nightdress | Bust | Usually a fall-away or slip cut |
Where Extended Sizes Actually Exist
This is the section most size guides leave out, and it is the one that saves the most wasted time. Availability above XL varies sharply by category, so it is worth checking before you settle on a style.
Across our 47 cotton sets, M, L and XL appear on every single style. 2XL is available on 32 of them. 3XL appears on exactly three — the Sand 5344A, the Peach 5344B and the Lavender 5349A. If you wear 3XL, begin with those three rather than browsing by colour and working backwards.
Occasion categories are different. All 19 styles in our babydoll collection are free size. In the bridal nightwear collection, 13 of 14 pieces are free size, with a single style — the long maroon satin nightdress — carrying graded S to XL.
What to Do When You Fall Between Sizes
Falling between two sizes is common and it is not a problem, provided you know which way to go.
For a two-piece set, take the larger size and choose a drawstring waist if the style offers one. A drawstring lets you adjust the fit yourself, which an elasticated waist cannot. For a one-piece, take the smaller size — a nighty gets its comfort from length and drape rather than from circumference, and the larger size will hang off the shoulders.
If your bust and hip fall in different sizes by more than one step, a two-piece set is the better purchase outright. Two separate pieces can accommodate different proportions in a way a single garment cannot, and this is the clearest practical advantage of the format.
Mistakes That Cause Most Returns
The most common error is buying to your usual top size and ignoring the hip. On a two-piece set the lower half is the limiting piece, and this single mistake accounts for the majority of size-related exchanges.
The second is assuming free size will fit. It is cut for a range, and if you sit outside that range no amount of drape will help.
The third is choosing a colour or a style before checking whether your size exists in it. Above XL, this wastes real time.
The fourth is skipping the chart because you know your size. Charts vary between styles, and thirty seconds of checking prevents a return.
What We Tell Customers in Store
This guidance comes from fitting customers in person at our store on Commercial Street in Bangalore as well as handling online orders, and one pattern dominates everything else.
Customers most often ask us whether they should size up. The answer is almost always no — and when someone has already bought a size up and come back, the complaint is never that the garment was too tight. It is that the waistband slipped or the shoulders dropped.
The second thing we tell people: if your top and hip measurements differ, stop looking at one-piece styles. A two-piece set will simply fit you better.

How This Plays Out in Practice
A frequent situation at the counter: a customer measures a 38-inch bust and a 44-inch hip, which places her in different sizes on the same chart.
In our experience the answer is straightforward. She buys a two-piece set sized to the 44-inch hip, and the top's built-in ease handles the bust comfortably. Had she bought a one-piece to fit the bust, it would have pulled at the hip; sized to the hip, it would have swamped her shoulders.
This is the single most useful thing to understand about nightwear sizing. The format you choose matters as much as the size you choose, and the two decisions are not separate.
The Details Most People Miss
Cotton shrinks slightly on its first wash. A well-made cotton garment is cut with a small allowance for this, so you should not size up to compensate. Wash cold and dry in shade and the fit holds.
Elastic loses tension over time while drawstrings do not, which makes a drawstring the better long-term choice if your measurements shift through the year.
And sleeve length is worth checking against your own build rather than the label. A size chart gives you circumference measurements, but it rarely tells you where the sleeve will land — and that is what determines whether the set feels right in a warm room.
Where to Start
If you are buying daily-wear cotton and want graded sizing through 2XL, our night suit collection is the widest option — 47 sets from Rs. 899 to Rs. 2,499.
If you wear 3XL, start with the Sand 5344A, the Peach 5344B or the Lavender 5349A.
If you are shopping an occasion category, expect free size in babydolls and most bridal nightwear, and check the single graded style if you need S to XL.
Frequently Asked Questions
How do I choose the right nightwear size?
Measure your bust and hip, then size to the larger measurement. On a two-piece set the hip usually decides, because the lower half has less ease than the top.
Should I size up in nightwear for comfort?
No. Sleepwear is already cut with relaxed ease. Sizing up typically results in a dropped shoulder and a lower half that will not stay in place.
What size is free size in nightwear?
It varies by brand, but free size generally corresponds to roughly M to L. It is cut to fit a range rather than to fit everyone.
Does nightwear shrink after washing?
Cotton shrinks slightly on the first wash, and well-made garments are cut to allow for it. Washing cold and drying in shade keeps shrinkage minimal.
What if my top and bottom sizes are different?
Buy a two-piece set and size it to your hip. The two pieces accommodate different proportions in a way a one-piece garment cannot.
Are plus sizes available in all nightwear categories?
Not equally. Cotton daily-wear sets carry the widest range — in our stock, 32 of 47 styles reach 2XL and three reach 3XL — while occasion categories are largely free size.
Getting It Right First Time
Choosing the right nightwear size reduces to three things: measure your bust and hip properly, size to the larger of the two, and resist the urge to size up. Add one more decision — a two-piece set if your measurements sit in different sizes — and you will rarely need to exchange anything.
