Rectangle Body Shapes: How to Rock Your Lines Like a Pro
Bodies aren’t cookie cutters, babe—they’re cocktails. A little of this, a dash of that, shaken up into something that only exists once: you. In other words, even if you technically fit into a body shape category, odds are you’re not just one thing. You’re a mix. You’re unique. You’re art. But today we’re talking about rectangle body shapes—aka the straight-line queens of the world.
Features
What even is a rectangle body type? Pretty much exactly what it sounds like: fewer curves and more sleek, streamlined vibes. Rectangle-shaped babes usually have busts and hips of about the same width, with a less-defined waist. A lot of the time this comes with a tall, slender figure—but not always. Think: chic and elongated energy.
Celebrity Rectangle Energy
Still unsure if you’re in the rectangle club? Look at Paris Hilton or Kate Hudson. If you see yourself in their silhouettes, congrats—you’re repping the rectangle body type.
Tips:
When it comes to swimsuits, it’s all about playing with lines, shapes, and patterns to fake a little definition and highlight your natural elegance. Here’s the cheat sheet:
Do:
-
Snatch that waist with styles that define it.
-
Pick traditional bottoms (skip the boy shorts, they won’t do you any favors).
-
Have fun with prints and patterns—they’re basically optical illusions for your figure.
Don’t:
-
Go for a straight-across neckline (rectangle + rectangle = box, not chic).
-
Hide in boxy silhouettes. You’re not a cube, babe.
-
Add volume up top without balancing below (hello, proportions).
Rectangle-Approved Geode Picks
Now the fun part: swimsuits that don’t just fit your rectangle shape, they flatter it.
Midnight and Rio Tankini
The deep V neckline? Instant waist. The cropped top? Chef’s kiss. Black is sleek and slimming, but if you’re in the mood for something bolder, this also comes in a playful patterned version—the Rio.
Indigo and Sicily Tankini
Asymmetry is your BFF, and this suit nails it. The cut gives structure while the cropped fit keeps your waist from disappearing into straight lines. Effortless, flattering, and so good for rectangle bodies. It even comes in the Sicily, a classic black, if you’re going for sleek and timeless.
Pacific and Terra One Piece Swimsuit
Defined scoop neck, open back, and a print that breaks up the straight edges? Perfection. This one brings a softer, more feminine vibe without trying too hard. And yes—it also comes in Terra if you’re feeling earthy chic.
Santorini One Piece Swimsuit
Square neckline, thick straps, and waist cut-outs = rectangle dream. The sky-blue paisley with ric-rac trim breaks up straight lines and the details give instant snatch. Wear it only if you’re ready to be stopped and asked where you got it.
Magnolia Bikini and One Piece Swimsuit
V-neckline, adjustable tie straps, and high-waisted bottoms in a ditsy floral = instant waist magic. A higher leg cut builds curves, while the neutral palette keeps it chic, timeless, and on repeat. Rectangle-approved and rewear-ready. Prefer more coverage? The one-piece version features a sculpting accent panel that highlights the hips in all the right ways.
Victoria One Piece Swimsuit
Black suit, delicate florals, and cream straps that tie into a bow front and crossover back. Translation: cinched waist and feminine lines for rectangles. The open back keeps it flirty, the details make it luxe.
Milan Tankini
High-neck top plus lace-up back = elongation and waist definition. The damask print adds dimension, while the high-waisted bottoms with a higher leg cut shape your rectangle frame perfectly. Sophisticated but still sporty.
Ebony Tankini
Notch neckline and laser-cut sides give subtle waist contouring without trying too hard. Paired with black high-waisted bottoms, it’s sleek, comfy, and flattering for rectangle shapes who like minimal with edge.
Willow + Jasmine Tankini
Double-strap V-neck and lace-up back = rectangle curve hack. Olive green keeps it chic, while the high-waisted floral bottoms balance it all out. Defined, flattering, and an easy summer staple.
Flora Tankini
Retro scoop neckline and warm yellow florals soften rectangle lines instantly. High-waisted bottoms with a higher leg cut create length and curves. A vintage-inspired must-have for straight figures.
Sol Tankini
Sweetheart neckline, keyhole detail, and honeycomb texture = rectangle flattery done right. Paired with high-waisted, higher-cut bottoms, this yellow floral set is feminine, comfortable, and curve-creating.
Georgia Tankini
Square neckline, gingham print, and criss-cross side cutouts do the rectangle heavy lifting. Seamless-waist bottoms smooth everything out while a higher leg cut keeps it long and lean.
Costa Bikini
Supportive straps, wildflower print, and gold clasp back give instant waist vibes. High-waisted, higher-cut bottoms balance coverage with curve. Rectangle bodies just got an upgrade.
Charlotte Bikini
Scoop-neck maroon floral top with adjustable straps = simple rectangle fix. High-waisted bottoms with a flattering leg cut add length and shape without sacrificing comfort.
Lotus One Piece Swimsuit
All-over smocking = built-in curves for rectangle frames. Sweetheart neckline and tie straps seal the deal with flirty, feminine shape. Easy, flattering, and timeless.
Peony Tankini & Bikini
Tankini for everyday, bikini top for flirty days — both rectangle-friendly. Sweetheart necklines, thick straps, and gathered-hip bottoms add waist and length, while the pale pink florals keep it soft.
Topanga Tankini
High-neck, long-sleeve coverage with a sleek floral print. Paired with high-waisted, higher-cut bottoms, it elongates a rectangle shape while staying practical for beach or surf days.
Costa and Paisley One Piece Swimsuit
Two rectangle-shaping legends, one flawless fit. The Costa serves up wildflower print with white trim, while the Paisley brings the same curve-making cut in retro pink florals. Both rock supportive straps, an open-back gold clasp, and a higher leg cut that adds instant length and waist definition. Pick your print, but know either one is rectangle perfection.
Daisy One Piece Swimsuit + Swim Skirt
Textured black-and-white floral and square neckline add dimension to straight lines. The skirt’s asymmetric drawstring and waistband create instant waist definition. Rectangle-friendly, chic, and functional.
The Bottom Line
Tips are cute and all, but the rule that matters most? Wear what makes you feel like a 10/10. Confidence outshines “perfect proportions” every time.
