Elastique Athletics Size Guide 2026: Nail Your Compression Fit, Inseam and Bra Size the First Time
Compression leggings are the one piece of activewear where "close enough" on sizing doesn't cut it. Too loose and you've paid $235 for regular leggings. Too tight and they sit in the drawer.
The good news: Elastique Athletics publishes clear measurement charts, four inseam lengths on its signature legging and a 60-day trial with free exchanges inside the continental US. This guide pulls all of it together from elastiqueathletics.com, checked in October 2026, so you can pick your size, inseam and style the first time.
Who This Size Guide Is For
It's for first-time Elastique shoppers stuck between two sizes, petite and tall readers who want to know which inseam to choose, and anyone weighing a beaded L'Original piece against the smoother Lisse line. We stick to fit, fabric and policy facts from the brand's own pages. We don't repeat wellness claims, and we haven't worn these ourselves.
Rule One: Snug Is the Point
Elastique's size guide sets expectations plainly: its pieces "generally run true to size and should fit comfortably snug." Compression is meant to feel firmer than a regular legging, so don't size up just because the first pull-on feels close. The brand's tip for anyone between sizes is to take the larger of the two.
The fabric explains the feel. The L'Original Lymphatic Compression Leggings list 57% polyamide and 43% elastane, a high-stretch blend that the brand says is sourced in France, OEKO-TEX certified, rated UPF 50+ and made in Portugal. The leggings also carry a stated gradient compression rating of 10–18 mmHg, running from ankle to hip. The Fierce Lymphatic Leggings are listed a touch firmer at 10–23 mmHg.
Elastique Leggings Size Chart
Measure your natural waist and the fullest part of your hips with a soft tape, then match both numbers to the brand's chart. If they land in different rows, go by the larger measurement.
| Size | US pant size | Waist | Hip |
|---|---|---|---|
| XS | 0–2 | 24.5"–26.5" | 34.5"–36.5" |
| S | 4–6 | 26.5"–28.5" | 36.5"–38.5" |
| M | 8–10 | 28.5"–30.5" | 38.5"–40.5" |
| L | 10–12 | 30.5"–33.5" | 40.5"–43.5" |
| XL | 14–16 | 33.5"–35.5" | 43.5"–46.5" |
Notice that a US size 10 appears in both M and L. That's exactly where the tape measure beats your usual label: if your hips measure 41", you're an L, whatever your jeans say.
Pick Your Inseam: Capri, Cropped, Full or Long
This is where Elastique gives you real options. The L'Original Lymphatic Compression Leggings ($235) come in four lengths; most other leggings in the range, including Lisse, Le Monde, The Fierce and Adorn, come in Cropped 25" and Full 27".
- Capri 21". Ends at mid-calf, so you can wear it with sneakers and ankle socks in warm weather or under a midi skirt. L'Original only.
- Cropped 25". A just-above-the-ankle length. A smart pick if you're petite and full lengths usually bunch at the ankle.
- Full 27". The standard ankle length across the range, the easy default for average height.
- Long 30". L'Original only, and the one tall readers should look for first: three extra inches over the Full length means the hem reaches your ankle instead of stopping short.
Buy the Long 30" if: regular leggings always leave a gap above your ankle bone.

Leggings That Stay Put: Stirrups and Waistbands
If leggings that creep up your calf drive you mad, look at the L'Original Lymphatic Stirrup Leggings ($275, in Cropped 25" or Full 27"). The stirrup sits under your foot to hold the legging in place, and the brand describes a seamless bonded high-rise waistband designed to reduce rolling and folding as you move. It's made from a breathable, fast-drying performance fabric, a nice match for long travel days and back-to-back errands.
Every other legging in the range uses a sculpting high waistband, with style details layered on top: Le Monde ($265) adds a tri-tone waistband, Adorn ($285) a scalloped hem, and The Fierce ($260) a black cheetah print.
Bras: Use Your Band and Cup, Not S-M-L Guesswork
Elastique sizes its bras XS to XL, but its chart maps them from your regular bra size, so start there.
| Cup | 30 | 32 | 34 | 36 | 38 | 40 |
|---|---|---|---|---|---|---|
| A / B | XS | XS | S | M | L | XL |
| C | XS | S | S | M | L | XL |
| D / DD | XS | S | M | L | XL | – |
| E | – | S | M | L | XL | – |
A dash means the chart doesn't list that combination. The L'Original Lymphatic Compression Bra ($150) is the high-support option, with optional removable inserts so you can adjust shape and coverage. MicroPerle beads sit along the back.

Bodysuits: Measure Your Torso Girth Too
One-piece styles need one extra number. Torso girth runs from one shoulder, down through the crotch and back up to the same shoulder. Elastique's bodysuit chart adds bust and girth to the waist and hip ranges above:
| Size | Bust | Girth |
|---|---|---|
| XS | 31"–32" | 56"–58" |
| S | 33"–34" | 58"–60" |
| M | 35"–36" | 60"–62" |
| L | 37"–39" | 62"–64" |
| XL | 40"–42" | 64"–66" |
If you're long-waisted, let girth decide. A bodysuit that's too short in the torso will pull at the shoulders all day. The Iconic Lymphatic Long Sleeve Bodysuit ($295) comes in brief or thong cuts, with a discreet hook-and-eye closure; the bead-free Iconic Compression Long Sleeve Bodysuit is $175.
Beads or No Beads: L'Original vs. Lisse
Same chart, different feel. Pieces with "Lymphatic" in the name carry Elastique's patented MicroPerle beads, small raised dots placed on the thighs and lower glutes on leggings. The Lisse line skips them entirely; the brand states plainly "No MicroPerle in the Lisse collection." Lisse Compression Leggings cost $150 against $235 for L'Original, keeping the same 10–18 mmHg rating and sculpting high waistband. Choose Lisse if you want a perfectly smooth surface under trousers or simply a lower price.

If the Fit Is Off: Exchanges, Returns and Care
- 60-day trial. You have 60 days from delivery to wash, wear and decide. Items should come back clean and in good condition, and refunds are processed within 10–14 days of the return arriving.
- Free size exchanges. Email bonjour@elastiqueathletics.com within the trial window; exchanges within the continental US are free. Outside the continental US, you cover return and exchange shipping.
- Final-sale exception. Last Chance and archive items can't be returned or exchanged, so be sure of your size before buying those.
- Shipping. Orders over $100 ship free within the continental US, and orders ship within 48 hours. International shipping is available with duties prepaid.
- Keep the fit you chose. The brand's care label says machine wash cold on delicate with mild detergent, skip fabric softener, hang dry and don't iron. Heat and softener are what wear down stretch fabric fastest.
Elastique Athletics Sizing FAQ
Do Elastique leggings run small?
The brand says its pieces run true to size and are meant to feel comfortably snug. If you're between sizes, it recommends the larger one.
Which inseam should I get if I'm 5'2"?
Elastique doesn't publish height ranges, so compare your favorite leggings: if their inseam is around 25", choose Cropped. Capri 21" is the shortest option, on L'Original only.
Can I exchange for a different size?
Yes. Exchanges are free within the continental US during the 60-day trial; email the brand's care team to arrange one.
Is the bra sized by cup?
It's sold in XS–XL, but the chart converts from band and cup, from 30 to 40 and A to E.
The Bottom Line
Getting Elastique right comes down to three numbers: waist and hip for leggings, band and cup for bras, girth for bodysuits. Expect a snug fit, size up when you're in between, and use the extra inseams to make the length fit your legs. With a 60-day trial and free continental-US exchanges behind you, the risk of a first order is low. Before you check out, see today's offers on our Elastique Athletics deals page.
