Vanity Sizing: Why Clothing Sizes Are So Confusing and How Tellar.co.uk Solves It

What Is Vanity Sizing?

Vanity sizing is when brands deliberately label clothes with smaller size numbers than the actual body measurements they are made to fit.

For example:

A UK women's size 12 in the 1980s might now be labelled a size 8 — even if the actual measurements haven't changed.

Brands use this strategy to make shoppers feel better emotionally, which increases sales. However, it creates major confusion, especially online.
