Apparently I'm a bra size 30GG!!!

Im the same, i was in 34 GG bras, lost a bit of weight and the fullness has gone from my boobs

went to be re measured expecting to be a 34, E or F but came out as a 32 GG, this bra fits perfectly, my others are very gappy at the top

Ive tried the boob or bust thing of wearing a very tight band. Its a concept that assumes your size is mainly based on your frame/build - how broad you are etc. But actually if you are a bit fatter this goes out the window!

When i was slim pre kids it worked ok for me but i am fatter now. Basically when you are fatter tight/close fitting things (sized to your underlying frame) dig into your fat . My underlying frame is not a 34 it probably is a 30, but because I'm overweight i find the snug fit uncomfortable and wear a 34. It probably is less supportive but tighter bands leave red marks.

Sorry it's likely they're going to change again when you fully stop so don't spend loads!

Most of the support in a bra comes from the band, so it needs to be snug and not move around.
If a non-stretchy tape measure will go round you, then the bra, which is elasticated definitely will.
If it feels too tight, hold the bra upside down, move the hooks to the front and do it up. It should be possible to pull the band out about an inch from your body. If it is much less than this, go up a band size. If it is about an inch, try increasing the cup size, because a cup that is too small makes everything feel too tight.

Try with trustworthy brands such as Panache, Freya and Fantasie. Or go to Bravissimo.

I used the boob to bust and was shocked at the size. I tried the one recommended though and it was a perfect fit and gave me a good lift. I wish I'd discovered it sooner.

I was a 30GG for years. You get most of the support from the band so it's best for that to fit correctly. If you've been wearing a sister size before then the right size may feel tight at first but it will support you better. If you're not sure then book a fitting at Bravissimo or an independent bra shop. Don't go somewhere like M&S where they add four inches on to the band size the give you a smaller cup size to make up the difference.

But yeah if you’re still breastfeeding don’t fork out on expensive bras, they are likely to change size again

I measured using b&b and found the band size too tight and I couldn’t really breathe!! So I went up a band and down a cup and felt better

It’s a plausible size. The vast majority of women wear a band size that’s too big and a cup size that’s too small.

I’m a 34GG/H but when I lost a lot of weight I was a 30-32GG.

If you have a Bravissimo near you, get them to fit you.

Buy lots of fab new shiny bras no matter what, you deserve it!

I know I am smaller (30E over here) but even at an E I most often wear a bralet as they are so small, don’t need much containment, and I don’t have a sport bra despite doing regular sports and running, they don’t really need it. I’m wearing no bra of any kind today and it makes no difference really!

In a world where we were raised to think Pamela Anderson had DD cups I think it’s important to claim back the perception of cup sizes be we large or small!

What dress size are you. Generally a 10 wood be a 30 back, 12 a 32 back etc. I always wore a 34 too until I did boob and bust and am now is a 30 which actually fits so much better. It’s a bit of a shock at first as the band is snug but that’s what is important to give shape and support. Could you go to a Bravissimo for a fitting?

@TheChosenTwo I think we're boob sisters. By BoB I'm 32F, if I put that bra on there's nothing to fill it. I get 32B or C depending on the cut.

I always used to wear a 34B. I did the boob or bust method and came out a 32E. I have tiny boobs, no meat on them at all! I ordered a bra in that size from M&S and it fits fine. The cup is bigger and goes under my armpit (which I think it’s supposed to), but the volume of the cup is very small if that makes sense. Like strapping two pancakes to my chest. It takes a bit of getting used to the fit, and to be honest I rarely wear a bra as I don’t need the support (usually just wear a crop top under a top).

The 32DD is a sister size of the 34D

I found boob of bust to be utterly useless for me, I’ve got absolutely no volume in my boobs at all so when I do the leaning over measurement it presumes I’ve got volume to match the measurement - I haven’t!
I’ve used it to try a huge variety of bra styles but they just don’t fit at all, way too big. I don’t have much in the way of fat. I just now pick up a bra off the shelf in my back size (about 30) and go with a B. It’s comfortable and if I choose the style right there isn’t a load of excess cup.
So many people rave about BoB so it obviously works for most but I have very wide set boobs with a big gap of nothingness in the middle and they’re generally small and saggy - it doesn’t work for me so I just go my own way 🥴

How long since you stopped BFing?

I wouldn't rush to buy anything for a few months. My breasts seemed to shrink and shrink in the months afterwards.

Perhaps a supermarket cheap one for the meanwhile until you're settled?

A sister size is a bra with the same cup volume on a different size back. This is because cup size is relative to back size so a D on a 30 back is smaller than a D on a 36 back
So 34D = 32DD = 30E = 28F with regards to cup volume

All of us are shocked the first time we have a proper measurement not an M+S measurement

If pre-baby you had just guessed your size then a proper measurement is going to be a shock.

This is what I meant. The volume of the cup stays the same when the size by number increase

I was a 30GG before baby - I didn’t feel that big in a well fitting bra. I’m a 32H now.

I did a boob or bust measurement and I was very careful to follow the instructions. It told me I was a different size to what I had been wearing so I went and bought some bras in my 'correct' size. I couldn't even get the buggers done up at the back!

Yes it’s a plausible size. For example I’m a 32GG/30H
most women wear incorrectly fitting bras. If you’re now a 30 band it’s likely your 34DD was wrong in the first place.
band size is roughly clothing size+20.
the correctly fitting bras may well feel “tight” to begin with but the support mainly comes from the band not the straps.
you might find you need a different shaped cup now you’ve lost volume. I mostly wear balcony style as I’m bottom heavy and other shapes have gaping cups.
if you have a look at bra volume size 30GG doesn’t actually equate to massive boobs.
