I bought 3 of these from a store 5ish years ago and they are pretty much the only ones I've been wearing since. They've held up really well; I machine wash but hang to dry. I can't seem to find another brand or even style within the brand that fits quite as well. None of the colors I already have were available on Amazon, so I hope more are added eventually (but I didn't have the plain black and that works for me for now).
Some tips the employee told me 5 years ago in case it helps anyone: the part between the cups where the wires come together should rest all the way back against your sternum (without stabbing you, of course); the edges of the other ends of the wire should cover all the breast tissue (this may be further back than you'd assume) and rest flat against the sides of your ribs; the cups should also rest against your skin (no gaps); and the support should come from the band, so you'll want the underwire to rest against your ribs with no gap, and the band should be tight on the loosest setting--as it wears out, you'll put it on tighter settings so that it continues to fit.
I think this style just happens to be perfect for how I'm shaped. I wear the 30G but the right size alone won't guarantee the perfect fit, as I've learned from trying other brands and styles. I'm sure I'm preaching to the choir but finding the right fit feels amazing so I hope that for everyone else too!
