Can anyone help with a bra intervention for DD?

[FlowerPotMum]

Pretty please..
Currently wearing and outgrowing rapidly a 28AA.
I've measured her and it's coming out as her chest (band) is 34 inch and the fullest part of her chest is 33 inch.
According to the method I've found online she's a 34 A cup. This doesn't seem right.
She's a slim 5 "2' 13 yr old in size 6/8 clothes.
She's also dying of embarrassment that I need to measure her. She also also died of shame telling me she needs padding as her nipples pop out in the cold!
Bless her little socks.. any advice would be brilliant. I don't want to take her to try any on without having a good idea of the sizes to grab.
Thank you.

I'm a size 6-8, and am a 28 inch band as well.

I'm a size 12/14 and am in a 32 band. There's no way your DD can be a 34 at her dress size

Doesn't always work this way - I'm a size 18 and a 32 band

All my fat is further down

My sister is a UK size 6 and her band size is 34. And she is an A cup with similar measurements (34,35). It’s possible if the boobs aren’t bigger than the band.

Suggest you take her to Victoria Secrets’ Pink if possible as it is the only place where she gets stuff that actually fits.

I am a 34 band and am a size 12.

😂 derelict! Mine is the same, it's on my my bum with me making buying clothes a nightmare!. You did make me chuckle.
She's definitely not a 34, I have no clue where I was looking and I measured her twice 🙄
The calculator is coming out with a 28 band then different cup sizes depending on how I tweet her other measurements ( she's at school and I never thought to do the leaning and standing ones required).
Victoria secret is her life's dream. We will see!.
Thank you all.

I think I would order 30B, C, D and go from there.
I don't imagine that she will want a really tight band at her age

Yes, that's the plan. Going at the weekend all being well.
