To find your right size in every shop, you need a tool that does three key things:
✅ 1. Uses your actual body measurements
Not weight. Not height. Just the numbers that actually matter for fit:
-
Bust/Chest
-
Waist
-
Hips
✅ 2. Compares these to each brand’s actual size chart
Every clothing brand uses different measurements—even for the same labelled size. That’s why a size 10 at Zara can be tighter than a size 8 at Whistles. You need a system that knows this.
✅ 3. Shows the best size for you, in real time, for each store
This means one profile = personalised sizing in 1,500+ brands instantly.
The Easiest Way to Do This:
Use Tellar.co.uk

-
Runs small, true to size, or large
-
Offers petite, tall or curve options
-
Is better suited to your proportions
