Taking the guesswork out of hunting down the elusive perfect bra size, opting for a professional bra fit really is priceless – quite literally, too, if you opt for the free M&S BraFit™.

As Annabel points out, having a second pair of eyes to help you decide on your perfect fit can really take the stress and pressure off finding a bra yourself.

“Aside from being on hand to assist with measuring, your bra fitter doubles up as a personal shopper. They can go and select some bras that fit the bill on what you’re looking for, and they’ll help you determine not only your size, but the style of bra you’d like, so you can leave the store with your perfect choice.

“Once you have your options, the fitter will leave you in peace so you can decide on the bra you prefer the most – so there’s no pressure, and no rush.”

If IRL isn’t your thing, you can also book an online fitting, where a friendly fitter will join you over video call, and use a mannequin to show you how the bra should fit. Just remember to bring along a tape measure, and you can have your camera off if you prefer.
