Simply Be Sizing Guide: How to Find Your Perfect Fit & What to Buy in 2025

Simply Be has earned its place as one of the UK’s most inclusive fashion brands, offering stylish and affordable clothing in sizes 10–32. But despite its inclusive size range, finding your perfect size at Simply Be isn’t always simple. Between vanity sizing, fit inconsistencies across collections, and fluctuating body shapes, many shoppers are left guessing.

At tellar.co.uk, we believe you shouldn’t have to guess. We help you find your size in over 1,500 brands, including Simply Be, using your real body measurements. Whether you're shopping dresses, jeans, swimwear, or occasionwear, our free sizing tool takes the uncertainty out of online shopping.

Why Simply Be Sizing Can Still Be Confusing

Even though Simply Be caters to a wide size range, their sizing isn’t always consistent across different categories or garment cuts.

Here’s why:

Bodycon dresses often run small due to stretch fabric.
Wide-fit footwear fits differently from standard UK sizes.
Plus-size denim collections may use vanity sizing—where a size 20 is closer to a traditional size 22.
Tops and blouses may be oversized or relaxed fit, depending on the line.

As a result, two people with the same waist measurement might need two different sizes in Simply Be’s trousers versus dresses.

Simply Be Sizing Tips by Product Category

1. Dresses

Simply Be offers wrap, shift, bodycon, smock, and midi styles—each fitting differently.

Sizing tip: Bodycon and scuba dresses run tighter. Size up if you’re between sizes, especially around the waist.

2. Jeans & Trousers

Their Curve jeans are designed with stretch, but waist-to-hip ratio can vary by cut (e.g. boyfriend vs. skinny).

Sizing tip: Check your waist and hip measurements before ordering. Tellar uses both to find the perfect cut.

3. Swimwear & Lingerie

Simply Be's bras, tankinis, and shapewear come in both dual and cup sizes.

Sizing tip: Their supportive swimwear tends to run small. Tellar calculates size from your bust measurement for better support.

4. Coats & Jackets

Winter coats tend to have a relaxed fit, while blazers may be cut closer.

Sizing tip: Use Tellar to compare outerwear measurements with your largest area (usually chest or hips).

What’s Worth Buying at Simply Be in 2025?

Here are the categories that consistently earn top reviews for quality, comfort, and design:

🌟 Best for Curve-Fit Denim

Their denim line, especially Lift & Shape and Bootcut Stretch, is designed to flatter curves. The internal support panels are a plus.

🌟 Top Pick: Occasionwear

Simply Be has become a go-to for plus-size occasion dresses. Look for brands like Joanna Hope and Yours London stocked on-site.

🌟 Footwear with Wide Fit Options

Wide and extra-wide options across heels, flats, boots, and trainers—especially useful if you struggle with standard UK fits.

🌟 Affordable Lingerie

Their in-house collections offer good support in sizes up to 46G. Look for multiway bras, seamless shapewear, and bralettes with support bands.
