The quality of this bra is excellent. The back support is the best. I do not feel anything, which is such an improvement. Before bras with this back support, the backs of my bras cut in me as well as moved up. I was constantly having to pull down the back of my bras. When I put this on, I forget about it. The straps are comfortable and stable. They contribute to the overall support.
Love the front opening. I only wear real t-shirts as home. I do, however, mainly wear knit tops that are a thin, slinky texture. The silhouette is smooth and do not see the seaming along the cup. It is also smooth in the back since it is staying put! That alone is a reason to buy this bra.

The straps are not adjustable. I do not consider that a minus with a support bra like this. It is difficult to make the wider and thicker straps adjustable. They are too long for me. When wearing a bra with adjustable straps, I always have to pull them up to about their shortest position. I think it ludicrous to complain about a bra without adjustable straps when they don't fit. The possible sizes between people is endless. Therefore, I shortened the straps. It does not take long to do, but now they fit perfectly. I would rather have these straps than thinner adjustable ones. As long as they are too long, it is easy to shorten. If they were too short, I would lengthen them b/c I sew, but I imagine most would just return.
There is one sizing aspect of this bra that I almost took away one star. I read the reviews and saw the suggestion to size up. There were enough that I did just that. I was a 40D at the time and ordered 42D. The fit around was fine and when I shortened the straps everything was fine. After I wore it a while I began to realize that the cup size really was a little too roomy. It was not terrible, but it really looked like the 40D would be better, however I figured it would not fit around since there was no wiggle room on this one.
I have been losing weight slowly and got this in July.
Instead of ordering a 40D in anticipation of losing weight I went ahead and ordered a 38D. I am writing this in Sept. Even though my measurements were 38, the bra did not close. I did shorten the straps as before. Everything was fine except for the fit around my chest. I went to the fabric store and got a bra extender. The longest one had 4 eyes to the bra's 6. I got another one with 3 eyes - cut off one row of eyes, stitched them together and worked fine. Now the 38D does fit my 38D measurements.
This bra has only one row of eyes. It is such a good support bra otherwise, I would encourage the company who makes it to add at least one row of eyes -- two would be better. No a lot of customers would add the rows, instead would send it back. I like a variety of bras, so when my weight has stabilized, I will buy another. It is hard to find this quality in a support bra. Knowing this, you need to either go up one size or buy your size and figure on getting a bra extender.
