What Clothes Styles Make You Look Slimmer? A Guide to Plus-Size Flattery in 2025

Looking slimmer isn’t about changing your body — it’s about choosing silhouettes that highlight your strengths, create balance, and boost confidence. Whether you're size 14 or 28, the right clothes can instantly enhance your proportions, elongate your frame, and sharpen your silhouette.

In this guide, we cover the best plus-size styles that create a slimming effect, what to avoid, and how Tellar.co.uk ensures the fit is perfect — whatever your shape.

Slimming Style Starts with Fit

Before we talk about silhouettes, here's the golden rule: nothing looks slimming if it doesn't fit properly.

Clothes that are too tight will accentuate lines and bulges
Clothes that are too loose will add volume and make your frame look wider

Get the fit right first — and that starts with Tellar.co.uk. Simply enter your bust, waist, and hip measurements, and Tellar will tell you your size in over 1,500 brands instantly.

The Most Slimming Clothing Styles in 2025

1. Wrap Dresses and Faux-Wrap Tops

Accentuate your waist
Create an hourglass shape
Soft draping flatters the bust and midsection

Why it works: The diagonal line of the wrap draws the eye across the body, breaking up width and elongating the torso.

2. V-Necklines and Deep Scoops

Draw attention upward
Elongate the neck
Break up a broad chest

Avoid: High crew necks and turtlenecks unless paired with long necklaces or open layers.

3. Vertical Elements

Longline blazers, waterfall cardigans, vertical stripes
Create the illusion of length

Style tip: Choose coats or cardigans that hit mid-thigh and wear them open to frame the body.

4. High-Rise Trousers and Jeans

Tuck in the waist and smooth the belly
Avoid muffin top
Elongate the legs

Best styles: Straight-leg or slightly flared trousers. Skinny jeans work if the fabric is structured and paired with the right top.

5. Dark Wash Denim

Slimming, classic, and versatile
Holds its shape better than light-wash or overly distressed jeans

Go-to brands: Levi’s 311, M&S Magic Shaping, and Good American — all available via Tellar’s lookup tool.

6. Monochrome Dressing

Dressing in one colour from head to toe elongates the body
Try black, navy, camel, or tonal shades

Style tip: Add interest with texture (e.g. a ribbed jumper with a smooth satin skirt).

7. Tailored Blazers and Structured Jackets

Add definition to your shoulders
Cinch the waist
Pull together the entire outfit

Avoid: Boxy jackets that cut off at the hip with no taper.

8. Midi Dresses with Defined Waistlines

Mid-calf length dresses visually stretch the lower body
Ruching, pleating, and darts shape the torso without clinging

What to Avoid If You Want a Slimming Effect

Shapeless oversized pieces: While comfortable, they often add unnecessary volume.
Drop-shoulder tops and batwing sleeves: Can make the upper body appear wider.
Bold horizontal stripes: Unless carefully placed, they widen the area they sit on.
Chunky fabrics with no drape: These can box in your silhouette.

Instead, go for clothes with weight and flow — soft tailoring, ponte knits, stretch crepe, and jersey blends are ideal.

Do Baggy Clothes Make You Look Bigger?

Not always — but if worn without styling, they can. Here’s how to make relaxed styles work:

Pair wide-leg trousers with a fitted top or tucked blouse
Layer oversized cardigans over a belted waist
Choose boxy blazers with sharp shoulders and wear them open

It’s all about contrast. Use volume somewhere, but not everywhere.

Final Style Tips for a Slimming Effect

Use belts to define your waist (over dresses, coats, and jumpers)
Opt for pointed shoes to elongate your legs

Own your look with confidence
