It drapes well (NOT FORM-FITTING), is decently flattering, and is even long enough for my 5'10" frame. I'd buy it again.

Fabric is a thin double knit.  It was very loose in the waist.  I wear a 12, have a 35" waist, and got the size listed.  I think the waistband is 4" too large.  But it drapes nicely over my butt, and it is wearable because I just let it sit on the top of my hips, which are 42".  For the price, a decent item.

Cute, drapey fit throughout which is flattering.  Sleeves and shoulders fit well.  Neckline is a little cheaply made and doesn't lie as stiffly/nicely as I would like but good for the price.

This is a good drapey fabric that hangs very well. My only qualm is that it's quite sheer, so the best way to wear it is to just wear an obvious bralette instead of trying to be coy with a nude bra.

Fits loosely, which is fine. I was looking for something that would truly "cover it up" so the length is good. However it is sheer and I didn't think it would be, just from looking at the pictures. Pretty color in the dark blue. The embellishing around the neck doesn't look like it will stay on for very long, but we'll see.

Stretchy material, so it's pretty snug. The material is soft and seems pretty well made. It's decent but not that wonderful for the price. I needed it right away, or I would have tried to find something similar in a store. The color is beautiful and my sister who ordered the same shirt loved hers. She has a tiny waist and it was much more flattering on her than on me (I have some more curves.)

Although this is listed as a "cotton blend" it definitely has some spandex (or something similar) since it has a lot more stretchiness than expected. It clings even if the fit is slightly loose, so if you don't like a clingy look, this may not be the best choice.

I got this for my partner who is between a size 6-8 in US women's sizes, so I got the XXL size based on the manufacturer's warnings about sizing. Even so, it was a little fitted looking. Not tight, but not loose either. Given the cut, the bottom half of the shirt flares out and is loose, but the chest-to-waist part is very fitted. Since XXL is the largest offered, if you're above an 8 Womens size, it will be on the tight side.

While the relative looseness/clingy feel is subject to personal preference, the construction quality is more objective. I was not too impressed with the stitching or the finish. Both sleeves had several 9" long threads hanging off them which I had to cut off. Hopefully the stitching in the sleeves will hold and not unravel. On the plus side, the fabric is reasonably thick for a summer garment, and not so thin as to be sheer or see-through in any way.

I give it 3.5 stars, rounded up to 4 due to the price point. It's a decent item, but not something I'd rate as a must-buy.

Is lined, has a lovely metallic sheen, and drapes well. Not a blackout curtain if that's what you're looking for.

It's not bad! It's not super slim as the image suggests but hey it'll do the job, especially if you want to layer up. Pretty good for a fair price(:

Fits well, pretty enough that you don't mind if it shows a bit under your dress

It's a little difficult to tell from the black shirt photos, but this shirt has a solid front and a sheer back (with sheer trim over all).  It's cut in the current trend for yoga shirts, which I would describe as "trapeze" - that is, fitted on top and flaring out towards the hem, somewhat of a triangular shape.  There isn't a lot of give in the bust, so I'd recommend going loose.  If you're a D cup I'd recommend the large size.  Unless you're a lot larger in the belly than around the bust, you're going to have a loose fit around your midsection, but that's the look it's going for.  The pictured model DEFINITELY has it pinned.

I like the sheer back, it does breathe very well and it is nice and flexible.  The cutout isn't enough to make the back look saggy, but it does show off my printed sports bras, which I think is fun.

So far it has held up fine in the wash, but I haven't been putting it in the dryer because the sheer fabric seems a little delicate.

This has turned out to be pretty well perfect for me, and the carrying strap makes it easy to hang from the closet door.  If I were beating up on it, I'd be looking for some kind of cover for it, but it really doesn't need it for me.  My only caution might be to consider that you check the width against your needs - it's fine for me, but I'm a reasonably small woman, and old as hell so I don't exactly throw myself around.  Anyway, when this one wears out, I'll be looking for another one like it from the same company.

This is a little wide in the legs, and on my 5'3" frame, that makes me look a little...wide? frumpy? If I were back to my  more athletic tone (average/thin at present), it might be more flattering, hang better. The quality of the material also doesn't look amazing and is easily wrinkled. The bandeau elastic is good though, and could definitely be worn without the halter ties, which actually feel more just for looks than actual support, as the elastic does the job. Both ways look good. Will wear this on casual summer day-to-day but wouldn't wear to an "event", personally. Though, could easily be dressed up a bit with a pair of wedges and some jewelry.

It fits well, and it drapes well. However, I thought the fabric would have a more polished look like jersey knit. I ordered a white one, thinking it would pair well with dress slacks for work.  It is a super thin, t-shirt-like fabric that would more appropriately pair with jeans.

It looked weird and unflattering with that sewn in white lining. However, I liked how this top draped on me, so I didn't return it. Instead, I took scissors and cut out the white panel, just leaving it a nice drape top. I will wear it with my own cami or tank top underneath.

I got this as a throw-on summer casual dress. I'm normally an XL in tops and dresses so that's what I ordered. It fits well. It's pretty flattering. And it's casual. It's perfect really. The size seemed pretty much right on. The fabric has some stretch which is what makes it look and feel more casual.

The fit of this dress is a little strange, but I'm mostly happy with it.  The fabric is nice.  It has a good, cottony feel to it, think enough to not show underwear lines through, but with plenty of stretch.  I got the XS/SM, I'm 5'5" and about 115lbs.  It is on the longish side, hitting right at my knees, and it is pleasantly slimming without being too tight through the body.  However, the sleeves are very, very tight, and the wide neckline gaps a lot.  It is fine for me. I bought it as a layering piece and I wear it to work with tights, a cardigan or blazer, and a scarf of some kind.  I am very happy with how it all comes together, but I'm not sure that I would ever wear the dress by itself, because of the awkward fit of the neckline.
