Brand Size Decoder
The same printed size fits differently across brands because each house cuts to its own block: different cup depth, band elasticity and wire width under identical labels. Pick your measured size and a brand, and the decoder tells you how that brand typically runs and where to start.
A 34DD at Victoria's Secret is cut shallower and stretchier than a 34DD at Freya. Neither is wrong; they are different garments wearing the same name.
How this brand runs: Cups run about half a size shallow and bands stretch generous.
Starting size advice: Start with your measured size; if between cups, size the cup up.
Brand variance notes reflect commonly reported fit patterns and each brand's own chart conventions; individual styles within a brand still vary. When in doubt, the brand's published centimeter chart beats the printed size.

Why brands drift from the standard
Mall brands cut for the average of their core market and err stretchy, because comfortable-in-30-seconds sells in a fitting room. Full-bust specialists cut firm bands and deep cups because their returns data punishes under-support. Fashion houses cut shallow and pretty. Once you know a brand's bias, you can walk in with the right starting size instead of burning three fitting-room rounds discovering it.
Our variance notes reflect each brand's own published charts and consistently reported fit patterns, and styles within a brand still vary. Treat the decoder's advice as your first try-on, and let the 10 fit checks make the final call.
