Bra help

[Trinpy]

I'm trying to find a new bra(s) but my boobs are a bit knackered after 2 babies and nothing fits anymore .

I'm a 28e. I usually go with Panache or sometimes curvy Kate - other brands I end up with the wires sticking into me at the sides. I just bought the Tango Classic and the Porcelain plunge. Tango was agony to wear; the cups cut into my boobs at the top towards the centre of the bra, the central gore was a bit too wide and at the bottom the wires kept digging into the breast tissue, even though the band seemed a snug fit and I'd hoiked my boobs up into the cups quite aggressively beforehand! The Porcelain plunge bra was much more comfortable but again had overspill towards the middle of the bra where the edge of the cups was digging in and the central gore was still a little bit too wide.

Ideally I want something at least slightly padded and smooth so I can wear it under tshirt and vest tops in the summer.

I have an ancient Panache Porcelain strapless bra in 28f that fits me perfectly but all other 28fs that I've tried on have been far too big .

I don't have a Bravissimo or anywhere else near me that sells bras in my size so would have to order online. Please help!
