Looking slimmer has nothing to do with starving yourself or squeezing into something two sizes too small. It's about understanding how fit, colour, and proportion work, and using them on purpose.

Shapewear is one tool in that kit. Not a magic fix, not a requirement. Just a practical option that, when used correctly, can help your clothes sit better and you feel more comfortable in them.

Styling tricks that work instantly

Colour does more than you think

Dark colours recede visually. Light colours come forward. This isn't a myth; it's basic optical perception.

Wearing a single colour from top to bottom creates a long, unbroken vertical line that reads as taller and leaner. A navy jumpsuit, an all-black outfit, or a camel co-ord all achieve this.

If you want to draw attention upward and away from hips or thighs, try a brighter or more detailed top with a darker bottom. This shifts the eye and creates a more balanced silhouette.

Avoid strong horizontal colour-blocking across your widest point. It emphasises width rather than length.

Fit is the real game-changer

Clothes that are too big often make you look larger, not smaller. When fabric billows and bunches, it adds visual bulk that isn't there. Well-fitted clothing (not tight, just fitted) follows your actual shape and looks polished.

A few fit principles that work for most body types:

High-waisted bottoms define the narrowest part of your torso and lengthen the legs visually

A-line skirts and dresses skim hips and thighs without clinging

Structured tops create definition at the bust and shoulder

Wrap styles create a waist-defining V-shape that flatters almost every body type

Layering with intention

Layering can either add bulk or create shape, depending on how you approach it. The key is keeping layers close to the body rather than stacking volume.

A fitted blazer over a slim-fitting top adds structure and shoulder definition. A long open cardigan creates a vertical line. A tailored jacket defines the waist even when the outfit underneath doesn't.

Avoid chunky knits layered over fitted skirts, or oversized outerwear with voluminous trousers. The combination reads as shapeless rather than relaxed.

How shapewear actually helps

Good shapewear doesn't change your body. It smooths and supports it so your clothes sit better. No illusions. Just a smoother surface for fabric to drape over.

When worn in the right size and compression level, shapewear:

Eliminates visible lines and lumps under fitted clothing

Reduces fabric bunching and shifting

Provides light back support that improves posture, which changes how you carry yourself

Smooths the lower belly and hip area under dresses and skirts

Keeps tops tucked in and bodysuits in place throughout the day

Shapewear that's too small, too tight, or the wrong style for your outfit does the opposite: it creates bulges at the edges, restricts movement, and makes you uncomfortable enough to think about it constantly.

Which shapewear style for which body goals

Smoothing your middle and tummy: A high-waist shaping brief or mid-thigh shaper covers from waist to thigh, smoothing the belly and hip area without stopping at an obvious line.

Lifting and rounding the backside: Look for briefs with a butt-enhancing cut, slightly higher at the back and designed to lift rather than flatten. Some styles use shaping panels to create a lifted silhouette.

All-over smoothing under a dress: A shaping bodysuit gives the most comprehensive coverage. It smooths from bust to hip, keeps everything in place, and works under bodycon dresses, fitted gowns, and structured midi dresses.

Light smoothing for daily wear: A seamless bodysuit with light-to-medium compression is the most wearable option for everyday use. It smooths without restricting and stays comfortable through long days.

Thigh smoothing and anti-chafe coverage: Bike shorts or mid-thigh shapers are ideal under dresses and skirts. They prevent chafing, smooth the thigh area, and add comfort when walking.

A note on confidence

No styling trick or shapewear piece will make you feel good if you're wearing it out of obligation rather than choice. Use these tools because they make your favourite dress sit better, because you like the smooth, polished result, not because someone told you that you needed to look smaller.

Putting it together

Start with fit: wear clothes that actually fit your body now, not the size you used to be or plan to be. Use colour to your advantage with monochrome dressing or dark bottoms. Add structure where you want it through blazers, high waists, and wrap styles. Use shapewear as a foundation layer when you want a smoother surface under fitted clothes. And stand up straight: posture is free and makes an immediate difference.

No extreme measures. Just dressing that works with your body rather than against it.
