Advice needed for backless dress with big boobs

[supertayto66]

I got my wedding dress a few months ago and loved it initially. The shop staff and my friends said it will be fine with a sewn in bra or body tape. But the more I think about it, the more I panic and want to change it. The dress is beautiful but it is backless, with straps. Will I be able to comfortably wear it while being supported? If so can anyone advise on suitable bra?? At the moment I really want to buy a new dress and it's getting me down. Help.

How big are big? I'm relatively small but with obnoxiously big boobs for my frame (d cup) and I use the nood game changer bra often, bc love plunge necks, backless, etc. Your boobs will not move at all but it does depend on how big I think.

D cup is meaningless without a band size. I'm pretty flat chested at a 32D

Don't stress too much, @supertayto66, I'm sure you're going to look beautiful no matter what you wear!

I was really confused by this comment until I looked it up, had no clue that's how bra sizes are measured! I must be wearing the wrong size ...

There have been some great bra threads on MN over the years. They prompted me to get measured properly and buy new bras.

Avoid M and S for measuring. They use the wrong method.

Fitted. Not measured. Agree not m and s
