Good Price, Great Bra
Color: Dark Pink, Size: 44G
These bras are outstanding! Both the band and cup size fit are exactly as they should. Having bottom heavy breast means I always have to have a underwire. Lace material with underwire can be tricky for us with larger bra sizes, as the underwire can be uncomfortable and the lace tends to be hard and scratchy on the skin. A beautiful garment can become uncomfortable and tear easily, if not made well. That has not been my experience with these bras at all. I have purchased them several times. The material is nice and softens after it has been washed. They maintain shape and hold well. For this quality and delicacy, I would normally pay upwards of $60 per bra. With these, I get great price, quality material and excellent comfort, style and fit.

Holy S*** this bra is amazing.
Color: Black, Size: 42G
I’m sure you are coming here reading reviews thinking “I don’t know. No bra has ever fit me right before. How will I know this bra is any different?” And let me be the first to tell you I was right there with you. I have been bra shopping for what feels like forever. For context I am a G cup and finding bras that fit nice seems like something I’d only find in my dreams. I have gotten bras from Torrid, Victoria Secret, Lane Bryant, Kohls, Walmart, you get the idea. Yes I know there are plenty of other sites but I don’t want to spend $80+ for a bra! Between them either hurting like hell from the wire, feeling like I was wearing a corset that was made for a door, or having absolutely no support/coverage, I contemplated just wearing no bra at all. I had such “luck” that I thought “maybe if I wear a sports bra all the time these problems would go away.” You guessed it! They in fact did not. I even tried no underwire and sure the wire pain was gone but good ol back pain came in at full swing. I would have constant issues with spillage and not feeling supported (and DONT even get me started on the uniboob)that I began to think I was the problem. Fortunately, a couple of days ago, I had discovered HSIA. I can’t stress enough to you how wonderful this bra is. It’s not only supportive but it’s also comfortable, breathable, and full coverage. And a added bonus: IT LOOKS AMAZING. This bra has changed my depressive outlook on bras to the most positive outlook. So much so I’m wearing this bra FOR FUN. 10/10 would recommend. It fits true to size. Straps are comfortable, no pinching. Under wire is very comfortable and does not dig into my rib cage. There is no padding, but still feels/looks great. Some shirts you can see the lace material but they have another bra that is smooth (I bought that one too) that fits just as great. I personally did not experience any itching like some other people were saying but I’d say just give it a try. If you made it this far reading this just buy it and see for yourself :)

Delicate and pretty but does the job
Color: Light Coral, Size: 40DDD
This is a new brand of bra for me and I got it because it was recommended. Today I'm wearing it and have a few thoughts: 1) The straps are comfortable. In fact, the whole thing is comfortable. It doesn't look like it would be comfortable at all, but it's pretty nice. 2) I'm not so sure about the sturdiness. When putting this on this morning, the mesh actually ripped a little bit as I was positioning it around my torso after buckling the back together. This is how I put bras on: Turn it upside down and have the snaps facing the front, snap the snaps, then rotate it around your torso until it's positioned correctly, then flip it rightside up over your breasts. Is there some other way? I'm super afraid of ripping the delicate material now. 3) Despite how delicate the material is, it does have some give once on and holds my breasts well. 4) The fit is good. I'm normally a 40DDD. If I go up a cup size, then the underwire digs into my skin, so I want to avoid that. These seem a bit snug so as I wear it today, I'm going to watch for "spillage" where breasts start bunching up at the top. I know, that sounds so gross, but larger breasted ladies know what I mean! To answer some questions: Yes, it has adjustable straps. Are there bras that don't have adjustable straps that aren't sports bras? Yes, it is machine washable, though this is one of the first bras where I think I might actually need to use a delicates bag because the lace is just so delicate. It's very pretty, holds well, minimizes well, is pretty comfortable, but just a lot more delicate than I'm used to.

Great affordable bra
Color: Balsam Blue, Size: 38I
Best bra I have purchased! I wear a 38 I and this is without a doubt the comfiest bra I own. No side boob or uniboob! The fit is perfect and there is no spillage on the tops or sides and I'm not having to constantly adjust myself. I didn't think it was possible to find cute, supportive bra for under $40 but here we are. They also have great support for when I'm at the gym. I do tend to still put a looser fitting sports bra over the HSIA bra when I'm working out for my own comfort, but it's not really necessary and I would most likely be fine during my workout without the extra layer.

Cute but could be better
Color: Dark Pink, Size: 38DD
This bra definitely looks really good and has a sexy style to it. It does a decent job overall, especially for the price, but after trying two different bras from the same brand, I honestly liked the more expensive one much better. The lace on this one is pretty, but it shows through thin shirts and tighter materials. The underwire also started digging into my skin after wearing it for a bit, and the lace caused some irritation. The fit wasn’t bad, but the pricier version was noticeably more comfortable and fit better overall. For $16, this bra is still decent and looks nice, but if you’re deciding between the two, I’d recommend spending a little extra money on the more expensive one for the added comfort and better fit.
