SO very comfortable and supportive, but can't get the four hooks hooked in the back.
Color: Light Beige, Size: 44DD
I measured myself as described in listing and ordered 44dd based on that. The bra fits just right. It is super smooth and soft fabric and VERY comfortable! I especially like that it holds in the side boobs and the underwire does not poke out. I don't think I have ever had a bra before that actually stayed up on the sides! Maybe I have been wearing the wrong size?? I was skeptical and bought because of the free returns, but I am keep this one and one other style which is just as comfortable. THE ONLY THING WRONG AND THEREFORE 4 STARS is that I cannot hook the backs (4 hooks). The other one I bought was doable but with effort, this on I absolutely could not do and had to hook in the front and slide around. I don't know if there a fix for this but I will keep them because they are so dang comfy and supportive. And yes, they do minimize which is also wonderful for me!

Fits like a $100 bra
Color: Black, Size: 36H
I don’t know why HSIA bras are so comfortable. The underwire does not dig in. This is the third one I’ve purchased. This bra has a pretty lace pattern. I love it. Highly recommend.

Great bra!
Color: Dark Beige, Size: 38D
I have several different bras from this brand. This is a really good minimizer. It has a nice wide strap. I don’t love the clasp as it is covered in a hard material, but overall it is a good bra that you can wear all day under form fitting shirts.

Uncomfortable
Color: Light Beige, Size: 38DD
In my search for a comfortable well-fitting bra, I came across this one. Reviews were good, so I ordered one. Half way through the day, I had to take it off. This is the most uncomfortable bra ever. This one went on to the "uncomfortable pile" pretty quick Not full coverage and not supportive. Side coverage is pretty good but straps are thin and do not lift.

Best Bra for Top Heavy Girlies!
Color: Light Beige, Size: 40C
I tried HSIA in the past but non of the bras fit right but this bra is the best! I’m glad I gave HSIA another chance because this is the best bra I’ve ever had! I’m already top heavy and doesn’t add extra bulk. It’s comfortable and breathable. In top of all that it’s affordable!
