Bra Fitting advice

[LoadsaBlusher]

I have been following all the bra intervention threads and finally measured this morning and
measured 29 around ribs ,then 34 around boobs ,bending forwards ?
Im currently wearing 32 dd bras but they don't feel right ?
I have a local M & S that I could nip to today to get myself sorted with some new bras but havnt read the best things on here about their fitting service ?
Advice / recommendations would be really appreciated

How do the cups of your 32DD fit? The measurements suggest about 30DD, possibly 28E, but those cups are smaller than your current one.

I feel like I've got a bit of space in the cups
My boobs are much emptier after two kids plus I've lost a bit of weight recently so maybe that's contributing too
Would I try 30 dd in M & S ?

I don't have experience with their bras, I've heard that sizing can be a bit all over the place. So try around that size.

Thanks ,
will head in later for a few to buy and try on at home .
Just want to be nice and snug and supported for a long day at work instead of constantly tugging on straps ,cups etc ...

Just back from town with two M & S 30E and they are great
What a difference,never thought I'd be a 30 but it doesn't feel tight just firm like everything's in place ,even in the E cup my cleavage is pushed up and pert !
going online now to look at more ! Thanks
