Bra size help after weight loss

[McPie]

Five years ago I was 15 1/2 stone and had a fantastic full bust and I am now 11 stone and have anything but a full bust .
I basically live in sports bras these days but my sister is getting married in 2 months so will have to ditch the beloved kit and wear a dress for the wedding and the hen night .
I measure 31 1/2 under bust and 41 at 90 degrees which should make it easy but my issue is there is no filler! My breasts are concave on the outside so what size should I be looking at or am I destined to wear uncomfortable bras for life?

The shape of the bra is going to play a big part in getting a good fit.
I recently lost 4st and when heavier I always wore a plunge style bra however now these are useless as I've lost the fullness from
My boobs and only a balconette style works for me now.
Do you have a bravissimo shop local to you? Their fitting service is great.
Are you on Facebook? There's a really good Facebook page called fairyboob mother and she will assist in helping you find the right size.

Thank you there is a Bravissimo in Edinburgh so I think I will take a trip in this afternoon and see if they can help me find a bra that I can't smuggle a packet of crisps in like the one I'm currently wearing

It's the Edinburgh store I use and always find them helpful, so I hope they managed to sort you out with a new bra that you can't smuggle snacks in 😁
Once you get an idea of your size/shape of bra do shop around. My favourite bras are from Debenhams and are £20.00 much better than forking out £40-£45 as previously had to!

Thank you so much for the Bravissimo suggestion I am not long back, dh ended up with a mad day yesterday, and they were amazing. I walked away with a 30FF and it is low enough at the front for my dress for the wedding and as it doesn't ride at the back it is low enough for the back of the dress I have for the hen night.

Oh that's brilliant, glad to hear you're all sorted. Don't be surprised if it takes a bit of getting used to your new size, it shouldn't/won't feel uncomfortable but it will feel different/a bit trussed up until you get used to having everything firmly held in place 😁
