What Kind of Brand is Coast?

Originally launched as a premium high-street label in the early 2000s, Coast has transitioned into a fully digital-first brand focused on eventwear, bridesmaid outfits, jumpsuits, and tailored occasion pieces. The brand balances affordability with glamour, often featuring:

• Floor-length gowns and bodycon dresses

• Structured jumpsuits

• Tailored separates

• Petite and plus-size collections

• Bridal and bridesmaid edits

Coast has strong sizing coverage—but depending on fabric, cut, or collection, fit can be confusing. So how does it really compare?

Does Coast Run Big or Small?

Coast generally runs true to size, but some dresses and jumpsuits can feel snug at the bust and waist. Tailored items often require careful attention to fabric stretch and body proportions.

Let’s look at the specifics.

Coast Sizing Breakdown by Category

1. Dresses

• Coast dresses are often structured and form-fitting, especially in woven or satin fabrics.

• Stretch styles (jersey, knit) are more forgiving.

• Strapless and off-shoulder styles can be tight through the bust and rigid in the waist.

• Advice: If you’re between sizes, size up—especially for fitted eveningwear.

2. Jumpsuits

• Coast jumpsuits tend to have narrow torsos and tailored cuts.

• Some offer stretch at the waist; others do not.

• Long-leg lengths are standard—petite sizing may be better for under 5'4".

• Advice: Size up if long in the torso or curvy through hips.

3. Tops & Blouses

• True to size in most relaxed styles.

• Fitted bodices or structured pieces may be snug at the bust.

• Advice: True to size; size up for bust support or non-stretch fabrics.

4. Skirts & Trousers

• Waistbands tend to be accurate, but cuts are often slim or tailored.

• Pencil skirts and tapered trousers can feel tight across the hips.

• Advice: Stick to your usual size if straight or petite; size up for a curvier shape.

5. Coats & Outerwear

• Generally true to size, often designed with occasion layering in mind.

• Coat dresses and cropped jackets may feel snug if layering over heavier garments.

• Advice: Size up if wearing over eveningwear with volume.

Why Sizing Can Still Go Wrong

Even though Coast follows standard UK sizing, many shoppers misjudge their fit due to:

• Not knowing current body measurements

• Assuming fabric stretch that isn’t there

• Relying on brand size charts that don’t consider shape

• Shopping for events without trying on in advance

That’s why Tellar.co.uk was created—to eliminate the guesswork and get it right the first time.
