Plenty of activewear brands talk about inclusivity and then stop at an XL. Buffbunny Collection takes the opposite approach and bakes it into the size run itself, offering pieces from XXS all the way to XXXL with worldwide shipping. That single decision shapes everything about the line, from the fabrics it develops in-house to the way each legging and crop is graded across sizes. In this review we look at what Buffbunny actually makes, the signature NuBre fabric that anchors most of the catalog, and the kind of woman this brand is genuinely built for.
What Buffbunny Collection Stands For
Buffbunny describes itself as activewear created for a woman who embraces her fears and celebrates her uniqueness, with a stated goal of comfortable, stylish, and supportive pieces for all women. That is a familiar mission statement on paper, but the catalog backs it up in a concrete way: the same flagship styles are offered across an unusually wide range of body types, and the brand ships worldwide rather than limiting itself to one market.
The result is a line that reads less like a fashion drop and more like a wardrobe system. You are not buying one viral legging, you are buying into a family of leggings, shorts, crops, bodysuits, and accessories that all share the same fabrics, the same fit logic, and the same support philosophy.
NuBre Fabric Is the Heart of the Line
If Buffbunny has a signature, it is NuBre. This is the brand's own nylon and spandex blend, described as a dreamy, double-brushed material designed to feel like a second skin. Across the catalog, NuBre shows up again and again, in the Legacy leggings, the Micro Legacy leggings and shorts, the flare leggings, and the Karma crop tops, which gives the whole range a consistent hand-feel.
What matters about NuBre is not just softness. The brand emphasizes high stretch retention, meaning the fabric is built to bounce back rather than bag out, and a medium compression level that the brand says sculpts and supports without restriction. Buffbunny specifically positions NuBre for mobility workouts like Pilates, yoga, barre, and studio sessions, while noting it stays comfortable enough for everyday wear. That dual-purpose framing is the whole point: one fabric that moves from a class to the rest of your day.
Leggings Are Where Buffbunny Goes Deepest
The legging selection is the most developed part of the catalog, and it is clearly where the brand puts its design energy. The Legacy Legging is the anchor, an ultra high rise style with a butterfly three-seam back waistband detail and no front rise seam for a smooth look, made in NuBre with medium compression.
From that base, Buffbunny builds variations for different preferences. The Micro Legacy Legging keeps the same DNA but adds a slightly shorter rise and a micro butterfly three-seam detail with closer contour lines, described as a more refined, elevated finish. The Legacy Flare Legging takes the formula in a different direction with an ultra high rise, a tri-arch back seam, and a flared leg the brand says is proportioned to elongate without hugging the calf. There is even a Micro Legacy Short with a 4-inch inseam for warmer days, so the same fit family covers full length, flares, and shorts.
Tops and Bodysuits Built Around Support Levels
Buffbunny does not treat tops as an afterthought, and the brand is unusually specific about support. The Karma Crop, offered in colors from Lover Pink to Enchanted Teal and Berry Ice, has a built-in shelf bra, a soft V neckline, and removable bust pads, with a light to medium support level and a choice of regular or taller meet-and-greet lengths. It uses the same NuBre fabric as the leggings, so a Karma Crop and a Legacy Legging are designed to feel like one outfit.
For lighter coverage there is the Butter Square Neck Crop, made in a Butter nylon-spandex fabric with a square neckline, capped sleeves, and a light support level with no bust pads. For something more all-in-one, the Poshknit Scrunch Bodysuit offers a twist-back detail, removable bust pads, light to medium compression, and a build the brand says transitions from the gym to everyday life. The pattern across all three is clear labeling, so you can match the support level to the activity instead of guessing.
The Details and Accessories Round It Out
The catalog also extends into the small stuff that makes a wardrobe feel complete. Buffbunny offers quarter crew and half crew socks in three-packs, in both bright and neutral colorways, with cushioned footbeds, stretch-knit construction, and signature logo detailing. The half crew length is specifically pitched for a flattering scrunched look, and the brand frames the socks as easy pairings with sneakers, training shoes, or slides for both gym and daily wear.
It is a small touch, but it reinforces the larger idea: Buffbunny wants to outfit the whole look, not just the headline piece.
Who Buffbunny Collection Is For
After walking through the range, the ideal customer comes into focus.
Women Who Have Been Failed by Narrow Size Runs
The XXS to XXXL range is the clearest signal of intent. If you have struggled to find activewear that fits and flatters at either end of the size spectrum, Buffbunny is designed with you specifically in mind, and the graded fits on styles like the Karma Crop reflect that.
The Mobility and Studio Crowd
Because NuBre is positioned for Pilates, yoga, barre, and studio sessions with medium compression, this is a strong fit for anyone whose training is movement-led rather than heavy lifting. The fabric is built to flex and recover with you.
Shoppers Who Want a Coordinated Set
If you like your leggings, crop, and socks to feel like one intentional outfit, the shared fabrics and colorways make Buffbunny easy to build sets from rather than mixing unrelated pieces.
What Stands Out, and What to Keep in Mind
The biggest strength of Buffbunny Collection is consistency. The NuBre fabric, the butterfly waistband details, and the clear support labeling repeat across the line, so the catalog feels designed as a system rather than assembled from trends. The wide size range and worldwide shipping back up the inclusive mission in a tangible way.
The flip side is that Buffbunny has a defined point of view. The compression is medium and the fabrics lean soft and second-skin, so if you are after maximum high-impact compression for heavy running or lifting, you will want to match the support level to your activity carefully. For the movement-first shopper it is built for, though, that softness is exactly the appeal.
The Bottom Line
Buffbunny Collection is a focused, size-inclusive activewear brand that turns one in-house fabric, NuBre, into a complete and coherent wardrobe. The Legacy legging family anchors the range, the Karma crops and Poshknit bodysuit cover tops and support with clear labeling, and thoughtful extras like the cushioned socks finish the look. If you want comfortable, coordinated activewear that genuinely fits a wide range of bodies, Buffbunny earns a closer look.
