It seems to be common that plenty of us just don't know our bra size.
If you're in that bracket then you're in luck. M&S has launched a contact-free bra-fitting service perfect for Covid times.
As part of their re-opening, they've launched their 'Bring On' campaign.
They're offering virtual at-home bra fit appointments, where you can chat to an M&S expert via video. It's free and the session will only last about 20 minutes in total.
The online session is best done from a laptop or PC in a quiet, private space. You can join it from a phone or laptop too but you'll need to make sure you've the Microsoft Teams app downloaded.
You can find out more about their online appointments and book one over on the M&S website.
Around the world, studies have shown that around 80% of us are wearing the wrong bra size.
The ‘Bring On’ campaign is focusing on the products people are looking for online as we get back to some normality this summer.
