About Costarellos: Modern Romance with Couture Precision
Founded by Christos Costarellos, the brand blends classic Grecian influences with modern silhouettes. Known for its signature tulle gowns, embroidered lace, and fairytale bridalwear, Costarellos is a favourite for red-carpet events and elegant weddings.
However, like many European couture houses, sizing is traditionally structured and may not align with UK or US high street standards. This can lead to confusion – especially when navigating conversions between EU, UK, and US systems.
Do Costarellos Dresses Run True to Size?
Generally, Costarellos garments run small, especially in structured or boned pieces like corset gowns and bridalwear. Their EU sizing system is also based on numerical values (e.g., 36, 38, 40), which don’t always directly match UK dress sizes.
Here’s a rough conversion to guide you:
EU Size | UK Equivalent | US Equivalent |
|---|---|---|
34 | 6 | 2 |
36 | 8 | 4 |
38 | 10 | 6 |
40 | 12 | 8 |
42 | 14 | 10 |
However, these are only approximate. For accuracy, use your bust, waist, and hips to determine the best fit via tellar.co.uk.

.What to Buy from Costarellos: Investment-Worthy Pieces
Costarellos is known for showstopping craftsmanship. Here are the must-buy categories where finding your perfect size is essential:
1. Bridal Gowns
If you're shopping Costarellos bridal, fit is everything. Structured bodices, layered skirts, and lace panels can feel uncomfortable if you’re between sizes. Use Tellar to avoid unnecessary alterations.
2. Tulle Gowns and Maxi Dresses
These romantic silhouettes often feature fitted bodices and generous skirts, so sizing depends heavily on bust and waist ratios. Many designs are sheer or partially lined, so exact fit matters.
3. Eveningwear and Formal Jumpsuits
Costarellos jumpsuits and gowns may have tailored arms or torso seams that need precision fit. Don’t rely on your UK size – check measurements using tellar.co.uk.
4. Ready-to-Wear and Resort Collections
These pieces run closer to standard EU sizing but can still differ depending on fabric structure. Linen and silk blends tend to have less give than jersey or tulle.
How to Measure Yourself for Costarellos
Want accurate size recommendations? Grab a measuring tape (or request one here) and follow these tips:
Bust: Measure around the fullest part of your chest, keeping the tape level
Waist: Measure at the narrowest point, just above your belly button
Hips: Measure around the widest part of your hips and bottom
For best results, wear light clothing and stand straight without sucking in.
Input these into your Tellar profile to get exact sizing across 1,500+ brands – including Costarellos.
