Does such a bra type exist?

[Chickdaft]

Ok, for context I’m a size 22 with double D’s roughly. I ditched bras a couple of years ago as could never find ones to fit that did t ‘dig in’ or ride up the back and found bra crop tops which were amazing for comfort. However I find they squish your boobs together and create a sweaty mess at times and despite showering a not altogether pleasant aroma from said boobs squashed for long periods.
my question is has anyone found a bra top that separates the ‘girls and keeps them apart?
would also love to wear a long chain type necklace now and then that hangs nicely and does not look like it’s hanging or dangling off a cliff face and should have a mountaineer on the end bouncing off your midriff?

I obviously can't see your bust but I would be very surprised if your cup size is just DD being a dress size 22.
The reason your bras are digging in is likely because you are wearing the wrong size, in both band and cup size.
Get a tape measure. Measurement 1: under your bust.
Measurement 2: over your boobs.
Report back these two numbers (in inches).

No idea what the end bit is about but have you tried Molke?

Riding up suggests a back size that was too big and digging in may mean a cup size that's too small. You were likely wearing the wrong size and that's why you were uncomfortable.

I'm a size 20/22 and wear 36GG. I need underwires for support and shape

You're wearing the wrong size bra. You can measure yourself though

Im the same dress size as you - although 36FF. I thinknits impossible to get the separation with a crop top style - wires are needed! I wish it werent the case, but ive tried so so many over the years.

I currently love the M&S body range of bras, they are so soft - not as structured as the bravissimo / triumphs of the world, and probably not as supportive but my god are they comfortable! The straps dont dig in, and even with the wiring i can happily wear all day.

With a plunge, you can also wear the longer necklace / lower cut top :-)

Thank you all for the replies. I know I need to measure properly again. Lots of ideas there
