The best bra fitting services in London are free, widely available, and can dramatically improve comfort, support and how your clothes fit—but most women are wearing the wrong size.
An estimated 80% of women in the UK are wearing the wrong bra size. In many cases, this comes down to how often sizing changes. For example, weight fluctuations, exercise, pregnancy, hormones and medication can all have an impact. However, despite these changes, most women only get professionally fitted once.
💡 Expert tip: You should get a bra fitting every 6–12 months to maintain proper support and comfort.
Importantly, a poorly fitting bra doesn’t just affect how you look—it also affects how you feel. For instance:
- Too tight = digging straps and discomfort
- Too loose = lack of support and poor shape
So, if it’s been a while since your last fitting, this guide will help you find the best places in London to get professionally fitted—quickly and for free.
