This is the prettiest thing I've ever seen (although I am usually not a fan of pink). The only optical downside are the straps which are rather wide. As usual I cut off the bows as soon as I was done with the pictures.
The wires are rather narrow, narrower than I've ever worn them but no problem for me. The band runs about 2 cm loose (0.8 in) - which means I am starting on the middle hook, I might shorten in a few months. I might have bought it in 30FF but the boutique I visited did not have that in store. There is a tiny bit of space at the top of the cup but not enough to go down a cup size. I do also get a strap gap - with my short-rooted breasts that's almost unavoidable. The straps are not only wide but also thick which contrary to intuition doesn't make them feel comfortable but weird.
Overall it gives good support, especially if you consider the very thin material.

I do think you're in the wrong band size! If your underbust is 25", you should look for 26 bands. These are hard to find, I know. But 28 is definitely too big, especially in a model like this that is very stretchy in the band.
