Conturve Ultimate Support Wireless bra or similar - thoughts please

[OnDaysLikeThese]

I'm looking for the holy grail of bras that probably doesn't exist! I have a large bust, which unfortunately gravity isn't doing any favours. I used to wear underwired bras, but can't bear them now. My gallbladder problems make all bras feel uncomfortable, even crop top pull on ones. They don't provide enough support, anyway.

I'm thinking of buying the Conturve Ultimate Comfort Wireless Support bra (got the name wrong in the title, but can't edit it) but am unsure due to mixed reviews about their customer service if you need to return them. Do people who have bought them find them true to size, comfortable and supportive, and if you needed to return them how did it go? Any other thoughts on them are welcome.

I'd like other recommendations for supportive, comfortable bras that don't cost the earth, please. The other brand I've looked at is Miss Mary of Sweden. They're the absolute maximum price I can go up to, but ideally I'd rather pay less. Tia.

Bump. Can anyone help please?

I have 4 of them in different colours and really like them. They give uplift and a smoother outline under tops. I’ve not had to return them so can’t comment on that. Only thing is the sizing isn’t normal bra sizes - I’m a 36D in bra size and use a Large. They also wash well, I just stick them in washing machine and tumble dry them and they still look like new.

I like them depending on what I'm wearing. Under jumpers / sweatshirts they are great and very comfortable, but they don't give quite enough shape for wearing with fitted clothes.
I suffer badly with contact urticaria and really struggle with bras so have tried most, and these are my go to for comfort.
For when I'm wearing something more fitted I also have 3 Miss Mary of Sweden bras in nude, white and black. I can't remember the style name but they have wide padded straps and are just about tolerable for my skin.

Thanks for your replies, they're very helpful. I've just taken the plunge and ordered them in two different sizes, as I'm on the borderline. Hopefully one of the sizes will be right, but I've got bra extenders that I realised might come in handy if the band of the smaller size is a bit small but the cup size fits.
