Faithfull the Brand Size Guide: How to Find Your Perfect Fit and What’s Worth Buying

Known for breezy silhouettes, nostalgic prints, and ethically made garments, Faithfull the Brand has become a favourite among modern romantics and resortwear lovers. But if you’ve ever struggled with Faithfull sizing — especially when shopping online — you’re not alone.

That’s where Tellar.co.uk comes in. Our free, intelligent size tool helps you find your perfect Faithfull size instantly, based on your real body measurements — not just a size chart.

Why Faithfull the Brand Sizing Varies

Faithfull embraces a relaxed, bohemian aesthetic — which means many pieces are oversized, unstructured, or semi-fitted. While this makes the clothes comfortable and flattering for many body types, it also leads to inconsistency:

Elasticated waists and adjustable ties make some pieces forgiving
Structured bust seams and non-stretch fabrics make others rigid
Sizes are listed in AU/US and often don’t map perfectly to UK sizing

Tellar.co.uk handles all of this complexity for you by matching your personal measurements to brand-specific fit data, factoring in silhouette, fabric, and style.

6	XS (6)	80–82	62–65	86–88
8	S (8)	83–85	66–68	89–91
10	M (10)	86–89	69–72	92–95

14	XL (14)	94–97	77–80	100–103

🧠 Tellar Tip: Not all styles follow the same cut — Tellar highlights styles that run smaller or more oversized than average, based on fabric stretch, bodice structure, and fit notes.

Key Fit Categories: Faithfull Clothing Breakdown

1. Dresses

Faithfull is known for its flowy, romantic dresses — but sizing can vary dramatically based on the construction.

Smocked or elasticated styles (like the ‘La Lune’ dress) tend to be forgiving and flexible.
Zipped or structured dresses (like ‘Jeanette’ or ‘Amalfi’) are cut slimmer, especially around the bust.
Strapless and halterneck styles often require precise bust fit — Tellar takes your bust and shoulder measurements into account.

2. Tops & Blouses

Faithfull tops are typically cropped or boxy, with details like puff sleeves, tie-fronts or shirring. If you're between sizes, bust fit is often the deciding factor.

Fitted blouses may run snug across the chest and arms.

Tie-front and smocked tops offer more sizing flexibility.

🧠 Tellar Tip: If you have a fuller bust or broader shoulders, Tellar adjusts your recommendation based on top length and upper-body proportions.

3. Trousers & Shorts

Faithfull trousers often feature high waists and wide legs, flattering for most shapes but tight across the waistband on non-elastic styles.

Drawstring and elasticated waistbands offer sizing leeway
Side-zipped trousers tend to run small in the waist
Shorts are often cut very short — Tellar factors in rise, hip, and thigh measurements

4. Swimwear

Faithfull’s swimwear line is made from recycled materials and tends to fit small across the bust and hips — especially in bandeau or tie-side designs.

Tellar recommends sizing up in specific styles if you’re fuller in the chest or bottom.

What’s Worth Buying from Faithfull?

⭐ The La Lune Dress

Smocked through the bust, floaty throughout. One of the most flexible pieces for varying body shapes. Lightweight and ideal for summer.

⭐ The Santi Pant

A high-waisted, wide-leg style in natural linen. Looks sharp but wears soft. Size carefully around the waistband if you have curves — Tellar will guide you.

⭐ The Monikh Dress

This cut is more structured, making it ideal for formal occasions or holiday evenings. Requires precise sizing — best matched via Tellar.

⭐ Faithfull Swimwear Sets

Best for confident sizing. Tellar matches your bust and hip measurements to the specific cut of each bikini or one-piece.
