If you’ve ever shopped the Star by Julien Macdonald collection at Debenhams, you’ll know this high-glamour, high-street fusion can be hit or miss when it comes to sizing. Known for bold partywear, sequin details and red-carpet silhouettes at accessible prices, this diffusion line has earned a loyal following — but also plenty of returns due to fit confusion.
In this guide, we’ll explain how the brand sizes up, what to watch out for in different cuts, and how to guarantee your perfect size using Tellar.co.uk — the UK’s most accurate size tool for over 1,500+ brands.
The Julien Macdonald Sizing Dilemma
Julien Macdonald’s designs are famously figure-hugging and dramatic — often using stretch fabrics, mesh inserts, deep V-necks and cinched waists to create a sculpted look.
But in the Star by Julien Macdonald collection, sizing is not always consistent. Here’s what to expect:
-
Bodycon dresses can run small, particularly in bust and hip areas
-
Blouses and wrap tops may fit generously in the waist but tighter across the shoulders
-
Trousers and skirts vary depending on fabric stretch — some styles cling more than expected
-
Occasionwear often features non-stretch panels that limit flexibility in movement
Translation? You can’t rely on your “usual” UK high street size here — especially if your bust-to-waist or waist-to-hip ratio is higher or lower than average.

Best Pieces Worth Buying from Star by Julien Macdonald
1. Sequin Party Dresses
This is the signature category — bold, glitzy and perfect for occasions. Often sold in limited drops.
Size Tip: These run snug. Choose based on your largest measurement (typically bust or hips).
2. Structured Wrap Tops
Often in satin or chiffon, these elevate a casual look with shoulder padding and angled hems.
Size Tip: True to size if you’re narrow-shouldered. Otherwise, size up.
3. Tailored Jumpsuits
Great for weddings or evening events, these pieces combine stretch with shaping seams.
Size Tip: Prioritise your torso and bust length for correct fit — inseams tend to be generous.
4. Wide-Leg Trousers
Clean lines, good drape. Works well with fitted tops.
Size Tip: Waist may be tight if non-elasticated. Double-check measurement.
