Yes def, I had 335cc from 34a for my first BA which took me to a 36C or 34D in M&S, I’ve just had to have re-op as they were PIP and I’ve had 470 soft touch which should take me up a cup size.
Did you have unders or overs? You might even end up a D once you’ve fluffed as they say 125 cc = a cup size x
