Problem is that if what they suggest doesn't work they make you feel like you have tried every bra available in the UK and you are hopeless. They collectively make you feel hopeless, nice people, but clearly inexperienced and limited by their own products.
The reality however is that if you go to FigLeaves or Simply Be you will get access to an amazing choice, in amazing sizes and really good supportive properly made bras.
If like me you make the effort to go to Bravissimo and leave with nothing, feeling like it was the worst decision you've made in a long time, go and look at Elomi, Goddess and Fantastie bras online. Bravissimo is really over hyped and nothing special in my view!
