Why Rebecca Vallance Sizing Can Be Confusing

Despite being labelled in AUS sizes (which match UK numbers), Rebecca Vallance designs are often cut closer to the body than UK shoppers expect. Other complications include:

• Lack of stretch in most garments

• Boning or lining that restricts sizing flexibility

• Petite/short torso proportions in some jumpsuits and dresses

• Inconsistent stretch and fit between partywear vs daywear

That’s why Tellar.co.uk offers such a valuable advantage: it calculates your fit based on garment structure, stretch, and exact measurements, not just a label.

🎁 You’ll receive a free measuring tape and can reuse your profile forever. No more guessing. No more returns.

Final Verdict: Is Rebecca Vallance True to Size?

Not quite—expect a slim, structured fit. Dresses, jumpsuits, and suiting often run small due to boning, lining, and tailored cuts. Relaxed styles are more forgiving, but overall, precise sizing is crucial for comfort and silhouette.
