Rectangle Shape? These 2025 Outfits Add Curve to Your Feed

If you’re a rectangle body shape (shoulders, waist, and hips about the same width), you know the struggle: no matter what you try, it can feel like your clothes aren’t giving you the curve you want.

The truth? It’s not your body — it’s the styling. Rectangle icons like Mindy Kaling, Natalie Portman, and Kate Winslet prove you don’t need to be a size 2 to look sculpted. The secret is waist definition, balanced proportions, and smart layering.

And that’s where LookSky comes in. We’re not just another styling app. We’re your personal AI stylist — your fashion feed that’s already personalized to your body, color season, and vibe. Every look you see can be virtually tried on before you shop, so you know it’ll work in real life.

What outfits flatter a rectangle body shape?
The best outfits for rectangle body shapes add curve with waist definition, volume on top or bottom, and layered pieces that break up straight lines. Try puff-sleeve blouses with wide-leg pants, wrap skirts with belted knits, or paperbag trousers with cropped jackets. LookSky is your personalized fashion feed and virtual try-on tool that brings influencer looks straight to your body.

• Why it works: The mock neck and textured sleeves add volume and structure to the upper body, while the high-waist shorts emphasize the waistline and lengthen the legs. This breaks up the rectangle’s straight lines with visual shape.

• Shape bonus: Works especially well for petites — the short hem elongates legs while the tucked top defines the waist.

• Why it works: The slim tank keeps the torso sleek, while wide-leg palazzo jeans add volume on the bottom half, balancing proportions and creating curve. The high rise cinches the waist.

• Shape bonus: A rectangle’s best friend for casual looks — the dramatic leg line makes the waist appear smaller by contrast.

• Why it works: The trench coat’s tie belt creates a waistline instantly, while its crinkled texture adds dimension. Paired with slim leggings, it sculpts a top-heavy silhouette that flatters a straight frame.

• Shape bonus: Ideal for fall layering — the coat adds curve without bulk, and the leggings streamline the lower body for balance.

Expert tip: Choose a trench where the belt hits right at the waist — too low flattens the shape you’re building.

• Why it works: The sleek, fitted cut skims the torso and creates contrast when paired with voluminous or structured bottoms, drawing attention to the waist. The satin sheen adds dimension to a straighter frame.

• Shape bonus: Perfect for layering — tuck it into high-waist trousers or skirts to instantly define your midsection.

• Why it works: The wrap design introduces a diagonal line across the body, breaking up straight proportions and adding movement. The slit elongates the legs and adds shape through the hips.

• Shape bonus: Works especially well with fitted tops — it balances the waist while adding curve at the bottom half.

• Why it works: The tie waist cinches the midsection, while the soft texture and wrap neckline add volume up top. It sculpts a more defined silhouette for rectangle frames.

• Shape bonus: Layer over slim tanks or camis to build dimension and keep the waist as the focal point.

Expert tip: Belted is always a great option — it forces the eye to the waistline.

• Why it works: The fitted knit hugs the torso, while pleated detailing and the asymmetric split hem add movement and visual interest, breaking up a straight silhouette.

• Shape bonus: Pair with high-rise bottoms to highlight the waist and let the pleats create curve through the hips.

• Why it works: The high-rise fit pulls in the waist, while the straight leg keeps proportions long and lean without clinging. It creates balance for rectangle shapes without exaggerating width.

• Shape bonus: Tuck in tops or camis to make the most of the high waist and create the illusion of curves.

• Why it works: The cropped cut draws attention to the waistline, while contrast paneling builds dimension across the torso. The structured shoulders add definition to the upper body.

• Shape bonus: Best styled over slim pants or skirts — the cropped length sharpens proportions and keeps the waist the star.

Expert tip: Keep the jeans minimal so the ruffles command attention.

• Why it works: The ribbed fabric creates subtle vertical shaping, while the unique neckline draws the eye upward and adds detail to a straighter frame.

• Shape bonus: Fitted tops like this highlight the torso and set the stage for waist-defining bottoms.

• Why it works: The soft drape of velvet adds volume and movement through the legs, balancing proportions for rectangle shapes. The drawstring cinches the waistline for definition.

• Shape bonus: Works best when paired with a tucked-in or fitted top to avoid hiding the cinched effect.

• Why it works: A structured coat adds polish and vertical lines, while its length elongates the body. When worn open, it frames the waist and layers in dimension.

• Shape bonus: Camel tones soften the silhouette and pair easily with textured bottoms, keeping the outfit sleek but not boxy.

Expert tip: Look for coats with tie belts or seam details to reinforce curves.

• Why it works: The belted waist breaks up the straight lines of a rectangle frame, while the v-neckline draws attention upward. The knit fabric adds softness without bulk.

• Shape bonus: Works beautifully with tall boots — they add balance and elongate the legs while keeping the waist the focal point.

• Why it works: The cropped length emphasizes the waistline, while the structured leather and dropped shoulders build volume across the top half. This contrast sculpts curves on a rectangle frame.

• Shape bonus: Style it over high-rise jeans or skirts — the cropped cut sharpens proportions and makes your waist look more defined.

Tuck your tee in completely — untucked fabric cancels the cinched effect.

• Why it works: A slim, buttoned-up cardigan acts like a waist-defining top, shaping the torso and adding subtle curves. The fitted style prevents the rectangle frame from looking boxy.

• Shape bonus: Wear buttoned and tucked into high-rise pants for instant waist emphasis.

• Why it works: The fluid drape of satin creates movement through the legs, adding dimension to the lower half while elongating the body.

• Shape bonus: Best paired with fitted or cropped tops — the contrast highlights the waistline while keeping proportions balanced.

• Why it works: The cropped trench hits at the waist, instantly creating definition, while suede texture adds depth and interest to a straighter frame.

• Shape bonus: Throw it over satin trousers or dresses — the cropped cut sharpens proportions and makes the waist the focal point.

Expert tip: Keep the jacket structured, not flowy — sharp lines read polished, not frumpy.

Think contrast: add detail on top, curve at the waist, and movement on the bottom. Celebrities like Mindy Kaling, Anne Hathaway, and Queen Latifah all use these tricks to build flattering proportions. You don’t need a personal stylist or a box subscription — just the right fashion feed.

Can virtual try-on really show me curves?
Yes — LookSky’s virtual try-on lets you see how waist-defining pieces will look on your exact shape before you shop.

Is LookSky like Stitch Fix or other apps?

We hyper-personalize fashion to your shape, color season, and style so you don’t just get inspo. You get accurate outfits based on you that you can actually virtually try on and shop. Styling isn’t about changing your body. It’s about knowing what works for you, and LookSky puts that in your pocket.” — Samantha Shih, Co-Founder of LookSky
