LIVE! Sports Bra Size & Fit Guide 2026: Measure, Match Your Impact Level, Order Once
Most sports bra mistakes happen before the workout even starts: in the fitting room you skipped, ordering "a medium, probably" online. Then the band rides up during burpees or the straps feel like a vise by the cool-down. With a brand that ships from Brazil, getting the size and support level right the first time matters even more, because an exchange costs time and a $5 restocking fee.
So SweatproofGear pulled LIVE! Activewear's own size guide, measuring instructions and the support details from its sports bra product pages, and turned them into a step-by-step fit guide. Everything below comes from liveactivewear.com in October 2026.
Step 1: Measure Yourself the LIVE! Way
You need a soft tape measure and two minutes. LIVE!'s size guide gives these instructions:
- Bust: measure under your arms, at the fullest part of your bust, from one side of your body to the other.
- Waist: measure the full circumference at the narrowest point of your waist.
- Hips (for bottoms and one-pieces): measure the full circumference at the widest point of your hips.
The brand's "special hint" is worth taking seriously: compare these numbers with similar items you already own and like. If your favorite sports bra from another brand fits well, measure it flat and use it as a reference.
Step 2: Find Your Size on the Chart
| Size | Bust (in) | Waist (in) | Bust (cm) | Waist (cm) |
|---|---|---|---|---|
| XS | 32 – 33.5 | 24 – 25 | 82 – 85 | 61 – 64 |
| S | 34.5 – 35.5 | 26 – 27 | 87 – 90 | 66 – 69 |
| M | 36 – 37 | 27.5 – 29 | 92 – 95 | 70 – 73 |
| L | 38 – 39.5 | 29 – 30.5 | 97 – 100 | 74 – 77 |
| XL | 40 – 41 | 31 – 32.5 | 101 – 104 | 78 – 82 |
| 2XL | 43 – 44.5 | 34.5 – 36 | 109 – 113 | 88 – 92 |
Two things to notice. First, there are small gaps between sizes (for example 33.5 in to 34.5 in). If you land in one, think about the style: a high-compression running bra with fixed cups will feel snugger than a stretchy seamless yoga bra. Second, not every style comes in every size; many bras on the site are offered in S, M and L only, and sale styles are often down to one or two sizes.
Step 3: Match the Support Level to Your Workout
LIVE! tags its sports bras by impact level. Here is how the styles we checked are described:
| Impact | Styles (Oct 2026 price) | Good for |
|---|---|---|
| Low to medium | Voltstream Sports Bra ($42), Seamless Knit® Weave Bra ($52) | Yoga, Pilates, walking, mobility work |
| Medium | Race Pro® Reflex Bra ($78), Drop Shot Sports Bra ($68), Fit Green® Adaptiv Arc Bra ($58), LIVE! Symbol Hydefit® Adaptiv ($52), Laser Sense® Tide Racerback ($54 on sale) | Training, racket sports, steady runs |
| High | Hydefit® Adaptiv Ace Bra ($68), Race Pro® Cross Bra ($39 on sale), Grafeno Fresh Pro Sports Bra ($68) | Intervals, jumping, hard running |
A simple rule: the more your feet leave the ground, the higher the impact level you want.

Step 4: Choose the Fit Features You'll Actually Use
Adjustable bands and straps
If you're between sizes, adjustability is your friend. The Race Pro® Cross Bra has wide adjustable straps and an adjustable three-level back closure, and the Essential Power Intense Top pairs elastic straps with a regulator and a back hook closure. These let you fine-tune the fit as the bra relaxes with wear.
Front zips
Hate wrestling a tight bra over your head after a sweaty session? The Hydefit® Adaptiv Ace Bra has a front zip with a halter neckline, the Drop Shot has a reverse front zipper, and the Race Pro® Zip has a front zipper with full internal protection, according to the brand.
Removable or fixed cups
Most LIVE! bras use removable pads, slipped in through a small internal opening in the lining, so you can wear them with or without shaping. Running styles such as the Grafeno Fresh Pro, Race Pro® Zip and Hold 3-Pockets use fixed cups instead; on the Grafeno and Race Pro® Zip, the brand says the fixed padding "allows more freedom of movement."
Compression
The Race Pro® Reflex fabric (78% polyamide, 22% elastane) is described as high compression with "a firm fit to the body," while the Drop Shot and Hold 3-Pockets bras are medium compression. If you prefer a softer feel, the Seamless Knit® Weave (64% polyamide, 31% polyester, 5% elastane) is described as soft-touch with excellent stretch.
Step 5: Think About LYCRA® ADAPTIV
Several LIVE! bras, including the Allure Sports Bra, the Hydefit® Adaptiv range and the Hold 3-Pockets collaboration with Manu Cit, use LYCRA® ADAPTIV, which the brand calls an "inclusive technology" that adapts to different body shapes and movements. If you often find yourself between sizes, these styles are a sensible place to start because the fabric is designed to flex with you.
Step 6: Neckline and Back Style
- Racerback (Race Pro® Reflex, Drop Shot, Laser Sense® Tide, Symbol Hydefit®): keeps straps from slipping and frees the shoulders, handy for overhead moves and racket swings.
- Halter (Hydefit® Adaptiv Ace, Fit Green® Adaptiv Arc): highlights the shoulders and, on the Arc, adds a back opening for airflow.
- Criss-cross straps (TOP CROSS LIVE!): a medium-support style with removable pads.
- Square neckline (Seamless Knit® Weave, Athletic Pro Fuller, LIVE! Hydefit® Adaptiv): a cleaner line under tanks and tees.
If It Doesn't Fit: Exchanges and Returns
| Option | Rules |
|---|---|
| Return for refund | Within 30 days of delivery; unworn, unwashed, tags on, invoice included; Final Sale excluded |
| Domestic return label | Free; request it from ola@liveactivewear.com |
| Exchange | Within 30 days; $5 restocking fee unless the item was sent in error |
| After 30 days | Store credit instead of a refund |
| International | Returns accepted within 30 days; no exchanges; duties and shipping not refunded |
Because exchanges cost $5 and returns are free on domestic orders, it can be simpler to return a wrong size and reorder the right one. Either way, try the bra on at home over thin clothing and keep the tags on until you're sure.
