I've always found m&s bra fittings have been hugely inaccurate. I've been so many times and they've measured me wrong every time. However, their bras are great and very comfortable. For the bigger cups, (d+) I'd advise bravissimo, they're great with the fittings.
Thankyou ladies x
I've personally been using the primark top crops. They are stretchy so I've not needed to purchase any new bras. I will however buy some near my due date as I'll be breast feeding.
John Lewis Or just get sports bras until you are a steady weight / bra size
M&S for me ♥️
