Celebrating a Strong Silhouette
If your shoulders, waist, and hips are roughly the same width — or your shoulders are slightly broader than your hips — you have what's commonly called a "rectangle" or "athletic" body type. You might have a toned, straight frame with less dramatic curves, or you might be more muscular with a powerful build.
Either way, let's be clear: your body is strong, capable, and beautiful. The right lingerie doesn't "fix" anything — it celebrates your frame while creating the visual effects you want, whether that's added curves, softness, or simply gorgeous lines on your natural shape.
The Strategy: Creating Dimension
The general approach for rectangle and athletic body types is to add visual curves and softness where you want them. This doesn't mean disguising your body — it means using cut, fabric, and detail to create interest and dimension.
Three goals to keep in mind:
- Add volume at the bust and hips (if you want curves)
- Create the illusion of a defined waist (cinching, seaming, contrast)
- Embrace your strong frame with styles that highlight it
Bras That Add Shape and Interest
Bralettes
Bralettes are genuinely incredible on athletic and rectangle body types. Without a lot of bust volume, bralettes sit beautifully — no gapping, no awkward fit issues. They add a layer of femininity and softness to a strong frame without fighting your natural shape.
Best bralette features for your body:
- Lace — adds visual texture and softness
- Scalloped edges — creates gentle, feminine lines
- Halterneck or racerback — highlights strong shoulders instead of hiding them
- Longline styles — add visual interest and create a waist suggestion

Balconette Bras
Balconette bras are magic for rectangle shapes. They create a lifted, rounded shape at the bust with wide-set straps that complement (not compete with) your shoulder width. The horizontal neckline adds visual width to your chest, creating the appearance of a curvier upper body.

Push-Up Bras (When You Want Volume)
If you want to create more dramatic curves, a push-up bra adds volume where you want it. On a leaner frame, even light padding makes a noticeable difference. Don't feel pressure to go dramatic — a gentle lift is often all you need.
Our picks: Victoria's Secret Bombshell (for maximum effect), Lively The Push-Up, ThirdLove 24/7 Push-Up
Padded Plunge Bras
A padded plunge gives both lift and cleavage, which creates a curvy focal point at the bust. This is great under V-neck and scoop-neck tops where the effect is most visible.
Bottoms That Create Curves
High-Waisted Briefs and Bikinis
High-waisted bottoms are your best friend. They create a visual "waist" even on a straighter torso, and the line from waist to hip gives the illusion of a curvy lower half. The higher the waist, the more dramatic the curve effect.
Bonus: High-waisted styles look incredible with bralettes. The combination creates an hourglass-like silhouette on almost any body type.
Brazilian Cut
The diagonal cut of a Brazilian bottom follows the natural curve of your glutes and creates a rounded visual effect at the hip area. More flattering than straight-across cuts for rectangle shapes.
Lace-Trim Bottoms
Any bottom with lace trim, ruffles, or decorative edges adds visual volume and softness at the hip area. This is a subtle way to create curves without high-waisted construction.
What to Avoid
- Boy shorts without detail — they can emphasize the straight line from waist to hip. If you love boy shorts, choose ones with lace panels or ruching that break up the line.
- Very low-rise briefs — they sit at the widest part of a rectangle frame without creating any curve.
Sets and Bodysuits
Bodysuits With Waist Detail
A bodysuit with a defined waist — through seaming, a belt, mesh panels, or color blocking — creates an instant hourglass effect on a straight frame. This is the single easiest way to create curves.
Look for:
- Cinched or belted waists
- Contrasting panels at the waist (darker sides, lighter center)
- Lace or cutout details at the waistline
Babydolls and Chemises
Babydolls flare out from the bust line, creating an A-line shape that suggests curves at the hip area. They're incredibly flattering on rectangle and athletic body types because they add volume exactly where you want it.

Corsets and Bustiers
If you want dramatic curves, corsets and bustiers are designed specifically to cinch the waist and push volume to the bust and hips. Even a soft-boned fashion corset creates visible curves on a straight frame.

The Key Takeaway
Athletic and rectangle body types have an incredible advantage in lingerie: almost everything looks clean and polished on you. You don't have to worry about overflow, fit issues, or support challenges in the same way curvier body types do.
