Let’s talk about the number — or letter — on your underwear. The one you’ve been guessing at for years. The one you picked up in a store because it “seemed right” or because you’ve always been a medium and a medium is what you grabbed on autopilot, the way you grab the same brand of soap without thinking. Most women in India have never actually measured themselves for underwear. They’ve approximated. They’ve hoped. They’ve bought a three-pack and made peace with whichever one fits least badly. Probably fits has become the global innerwear strategy. It shouldn’t be yours.
Here’s the good news: panty sizing, once you understand it, is genuinely simple. Here’s the other news: you have to actually understand it first, because the industry has done a spectacular job of making it look complicated from the outside.
S, M, L, XL — and Also 28, 30, 32? What Even Is Happening
Walk into any innerwear section in India and you will encounter at least two different sizing systems existing peacefully side by side, as if this is completely normal and not mildly unhinged. Some brands use the familiar S/M/L/XL alphabet system. Others use numbers — 28, 30, 32, and so on. Some use both simultaneously, printed on the same label, which helps no one.
The numerical system, for what it’s worth, usually refers to waist size in inches — inherited from older garment sizing conventions. The letter system is a broader, more forgiving categorization that’s supposed to account for a range of bodies within each band. Neither system is universally standardized. A medium at one brand is an S at another and an L at a third, and all three garments may fit you identically or not at all. This is not your confusion. This is the industry’s mess. You’re just living in it.
What this means practically is that your size is not a fixed identity. It is a response to a specific brand’s specific chart on a specific day. The sooner you make peace with that, the more comfortable (literally) your life becomes.
First, Let’s Get the Tape Measure Out
Before you can decode any size chart, you need two numbers: your natural waist measurement and your hip measurement. These are not the same thing, they are not interchangeable, and yes, you do need to measure both.
Your natural waist is the narrowest part of your torso — not where your jeans sit, not where your leggings dig in, but the actual narrowest point, which is usually a couple of inches above your belly button. Stand up straight (no sucking in, this is a judgment-free exercise), and wrap the tape measure around that point. Keep it snug but not tight. Write that number down.
Now, your hips. The widest point of your hips is what you’re after — this typically falls around 7 to 9 inches below your natural waist, roughly where the fullest part of your seat is. Wrap the tape there. Again, snug but not cutting off circulation. Write that number down too.
Here’s the thing they don’t tell you prominently enough: for panty sizing, your hip measurement is the one that matters most. Panties need to actually go around the widest part of your lower body. The waist measurement helps, especially for high-waist styles, but the hip is your anchor number. If you’ve been sizing yourself by waist alone, that’s likely been the source of considerable elastic-related suffering.
So What Do the Numbers Actually Mean
As a general guide — and this really is a general guide, not gospel, because brands vary — here’s roughly how the letter sizes map to hip measurements: a Small typically fits hips between 83 and 89 centimetres. A Medium fits 90 to 97. A Large covers 98 to 104. An XL goes from about 105 to 112. Beyond that, brands increasingly offer XXL and extended sizes, though not nearly as universally as they should.
These ranges overlap at the edges on purpose — if you’re right at the boundary between two sizes, it usually means either could work depending on the cut and fabric. When in doubt, size up. A slightly roomier fit is almost always more comfortable than a slightly tight one. Your skin will thank you. Your day will go better. Small mercies, but real ones.
Your Body Is Not the Problem. The Fit Is.
Here’s how you know your panties don’t fit — even if you’ve been ignoring the signs so long they feel normal. The waistband rolls down throughout the day. The leg elastic digs into your thighs and leaves red marks by evening. You’re constantly adjusting, pulling, repositioning. The fabric bunches in places it shouldn’t. You can see lines through your clothing that you’d rather not. These are not signs that your body is the wrong shape. These are signs that the garment is the wrong size.
Too tight is the more obvious offender. Elastic that digs creates friction. Friction on skin that’s already warm and slightly damp from daily life leads to chafing — that specific, miserable soreness on the inner thighs or along the leg crease that makes you walk funny by afternoon. Waistbands that are too snug don’t just leave marks; they trap heat and moisture, which creates the exact conditions that lead to bacterial and yeast imbalances. This is not being dramatic. This is basic anatomy. Tight underwear in the wrong places is genuinely a health consideration, not just a comfort preference.
Too loose has its own problems, which people talk about less. Fabric that doesn’t sit properly bunches and folds, creating pressure points in different places. It shifts around as you move, which means constant friction in inconsistent spots. It also doesn’t provide the gentle support and coverage most styles are designed to offer, which rather defeats the purpose of wearing the garment in the first place.
The right fit is almost boring in how unremarkable it feels. The waistband sits flat. The leg openings sit smoothly without digging or gaping. There is no pulling, no rolling, no adjusting twenty minutes after you’ve gotten dressed. You forget you’re wearing it, in the best possible way.
Why Every Brand Has Decided to Do Its Own Thing
Brands size differently because there is no regulatory body forcing them to agree, and also because sizing is partly functional and partly psychological — both the brand’s psychology about how they want their clothes to feel, and assumptions about how customers want to feel wearing them. Some brands run large because they’re built for comfort-first construction. Others run small because their target customer is narrower in frame, or because vanity sizing works in reverse in innerwear (make someone feel like a small, and they feel good). None of this is logic. All of it affects your Sunday morning purchase.
What this means for you: always check the brand-specific size chart. Not the general internet guide. Not what you were last time at a different brand. The actual chart for that actual brand, matched against your actual measurements. Most decent brands now have these on their websites and on the back of their packaging. Use them. They exist for a reason.
Fabric matters here too, more than people realise. Cotton has very little give — a cotton brief that’s technically your size will feel snugger than a nylon-spandex blend in the same size, because synthetic fabrics have stretch built in that accommodates more variation. If you’re buying 100% cotton, you may want to size up one step compared to what you’d choose in a stretch-woven fabric. If it’s a blend with elastane, it will mould to you more forgivingly. This is not magic — it’s just fibres behaving differently under tension. Worth knowing before you open the packet.
The Number on the Label Knows Nothing About You
This part is important, and not in a vague, motivational-poster way. In a practical, worth-saying-plainly way.
The size on your underwear is a response to a measuring system that varies by brand, by country, by decade, and sometimes seemingly by mood. An L in one brand is an M in another. A 32 here is a medium there. These labels were invented to help fabric cut around a body — not to rank bodies, not to tell you anything meaningful about your health, your beauty, or your worth. They are a production shortcut. They are not a verdict.
Women in India are raised in a culture that has a great deal of casual, well-meaning, thoroughly exhausting commentary about body size. You’ve probably heard some version of it at a family lunch. You don’t need your underwear label adding to that chorus. Check your measurements, find your fit, and wear the size that actually fits your body — whether that’s an S, an XL, or something in between. Comfort is the point. Everything else is noise.
The One Thing to Take Away
Measure your hips. Check the brand’s size chart. Try the size that matches your numbers, not the size you’ve always assumed you are. If it doesn’t feel right — if there’s digging, rolling, or anything that makes you adjust it twice before you’ve left the house — it’s the wrong fit, full stop. Size up, try a different cut, check a different brand. You are not the variable that needs adjusting. The garment is.
You deserve underwear that fits. Not underwear that probably fits. Actual, comfortable, forget-you’re-wearing-it fits. That’s the baseline. Go find it.
