You've done it. We've all done it. Grabbed a size 14 because that's "your size," pulled it on, and stood there wondering if the waistband was designed by someone who has never met a human stomach.
Here's the truth nobody at the shops will tell you: your dress size and your legging size have never actually met. They're not related. They don't even work in the same units, not really. One brand's 14 is another brand's 10 is another brand's "generous 16," and none of them asked your body what it thinks.
At Nikki Whoops we got so sick of this mess we scrapped the whole numbers game. Sizes 6 to 26, organised into Curvy, Curvaceous and Curvalicious, built around actual bodies instead of a mystery formula dreamed up in a boardroom. Let's talk about why dress sizes fail you, and how to actually get leggings that fit.
Your Dress Size And Your Legging Size Are Not Friends
A dress is built to skim. A legging is built to hug every curve you own, stretch when you sit, and survive a squat without staging a mutiny. Completely different jobs, completely different measurements.
Your dress size is based on your bust, your shoulders, the drape of fabric that mostly just hangs there. Your legging size is based on your waist, your hips, your thighs, and how much stretch the fabric needs to move with you. Comparing the two is like using a shoe size to buy a hat.
So the next time a pair in "your size" doesn't fit, that's not a you problem. That's a sizing system problem.
The Vanity Sizing Con (And Why It's Not Your Fault)
Here's a fun bit of retail history. Over the past few decades, plenty of brands have quietly shrunk their size labels while keeping the actual garment the same, or bigger. It's called vanity sizing, and it exists purely to make you feel good standing in a changeroom.
The result? A size 12 in one shop is a size 16 in another. Nothing about your body changed between stores. The label did. It's a marketing trick, not a measurement, and it's precisely why "just buy your usual size" is the worst advice in fashion.
We built our sizing around real body measurements instead of a feeling. It's less flattering to the ego for about four seconds, and infinitely more useful when the parcel actually arrives.
What Curvy, Curvaceous And Curvalicious Actually Mean
Forget the alphabet soup of XS through 3XL. Our system is simple and it's built on you, not on vibes.
Curvy covers sizes 6 to 14. Think of it as our everyday, easy-fit range for smaller frames who still want that high waistband doing its job.
Curvaceous covers sizes 14 to 20. This is where a lot of "in-between" bodies finally get a fit that isn't squeezing or swimming.
Curvalicious covers sizes 20 to 26. Built with the same fabric, same waistband, same pockets. Not a scaled-down afterthought, a proper range designed for the body it's meant for.
Three names, one goal: you find your group by your actual measurements, not by whatever size you wore in year ten.
Measure Your Body, Not Your Wardrobe
Grab a soft tape measure. Not the metal one from the toolbox, that's a different sort of afternoon entirely.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug, not strangling. You're measuring yourself, not auditioning for a corset.
Hips
Stand with your feet together and measure around the fullest part of your hips and bum. This is the number that decides more of your legging fit than anything else, so don't rush it.
Write both numbers down and compare them to our size chart, not to the tag in your jeans. Your jeans have opinions. Your tape measure has facts.
The 12cm Waistband Rule Nobody Tells You
Most leggings roll down because the waistband is basically a glorified rubber band, thin, cheap, and only there to hold the fabric together at the top. Ours is 12cm high for a reason.
A proper high waistband distributes pressure evenly across a wider area of your torso instead of digging a single thin line into your skin. That's the difference between "comfortable all day" and "adjusting myself at the school gate for the ninth time."
If a pair's waistband looks more like a hem than a support structure, that's your first clue it's going to let you down mid-squat. Ours doesn't. Ask any nurse who's worn a pair through a twelve hour shift.
Between Sizes? Here's What Actually Works
You've measured, and you're sitting right on the line between two size groups. Now what.
Generally, size up rather than down. Leggings stretch to fit a bigger body far more comfortably than they stretch to cover a body they're too small for. A pair that's slightly roomy still holds its shape. A pair that's too tight loses its stretch recovery fast, and then you're back here again in three months buying another pair.
Also consider what you're doing in them. Gym session with a lot of movement? Go with the snugger of your two options. Couch, errands, school pickup? Give yourself the bit of breathing room. Comfort shouldn't be a negotiation.
Squat Test: The Only Fitting Room You Need
You cannot tell if leggings will hold up by standing still in front of a mirror. Nobody lives their life standing still in front of a mirror.
Do an actual squat. Bend all the way over. Sit down and stand back up like you would getting off the couch for the fortieth time that day. If the fabric goes translucent, the waistband slides, or you feel a tight band cutting in anywhere, that pair has already failed the only test that matters.
Our fabric is squat-proof by design, four way stretch that holds its opacity under pressure instead of turning into an accidental peep show. You shouldn't need a cardigan tied around your waist just to bend over safely.
Real Women, Real Reviews, Real Fit
We don't need to tell you our leggings are comfortable. Our customers already have.
"These leggings feel like you are wearing nothing, so comfy and soft, firm in all the right places but not tight even after eating… well worth the money."
Being plus size and self conscious about leggings is a real, common worry, and it's exactly why the Curvalicious range exists. One customer put it best after trying our anatomical butterfly print: "Being overweight was making me conscious about wearing leggings but the curvalicious sizing is true to form and its patterns i love."
Real bodies, wearing real leggings, saying real things. Not a stock photo in sight.
The Sizing Mistake That Ends In A Return
The single biggest fit mistake we see: buying based on what you wore five years ago, or what you wear in a completely different brand. Bodies change. Brands vary. Neither of those things is a personal failing.
The second biggest mistake is guessing instead of measuring. It takes ninety seconds with a tape measure and it saves you a return, a refund wait, and the faint sense of betrayal that comes with a parcel that doesn't fit.
Measure first. Match to our chart. Order once. Simple.
Comfort Shouldn't Be A Guessing Game
Your body isn't the problem. A sizing system built around vanity instead of measurements is the problem, and it's been gaslighting shoppers for years. Measure your waist and hips, match them to Curvy, Curvaceous or Curvalicious, and stop letting a random number on an old dress decide what you deserve to wear.
Bold prints. Comfy as hell. Zero apologies, and now, zero guesswork.

FAQs
Do Nikki Whoops leggings run true to size?
Yes, our sizing is based on real waist and hip measurements rather than standard dress sizing, so always check the size chart rather than assuming your usual number.
What if I'm between two sizes?
Size up. Our fabric holds its shape and stretch recovery better when it's not stretched to its absolute limit, and a slightly roomier fit still holds your waistband in place.
Why do Curvy, Curvaceous and Curvalicious use size ranges instead of one number per size?
Bodies aren't a single measurement. Each range spans a few sizes because hip, waist and thigh proportions vary even within the same size, so the ranges give you room to find your actual fit.
Will thinner fabric mean my size runs differently?
No, our four way stretch squat-proof fabric is consistent across the full range from Curvy to Curvalicious, so the sizing logic stays the same no matter which pair you choose.
What do I do if my leggings arrive and the fit's still not right?
Check our returns policy. We offer 30-day returns, so a wrong-size guess doesn't have to be the end of the story.
