Calvin Klein 2892 gives nice cleavage and lift, and it is great that is it both seamless and tagless. I do wish the straps were a tiny bit wider for better support, because at just 3/8" wide, they feel a little thin. The lace gets itchy after wearing for a long time, so this is not really an all-day bra. I bought it for special occasions and am happy with it.
This bra is a push-up. It has graduated foam with "inner cookies" on the sides to create cleavage. The cups are small for me (I believe I should be wearing the 32E) but I am keeping it for when I want cleavage as some clothes can hide the quadboob pretty well. The center gore is odd: it's not very wide on top but it flares more than usual (it's 6 cm wide at the bottom).
The inner part of the cups is really soft and I am now wearing it on my sensitive/itchy skin days even though the fit is not too good.
Finally a bra that actually fits! Like many I'd worn the wrong size for years, so I followed Bratabase's measurements and recommendations and order this bra based on those. For reference my sizes are 30DD/E and 32DD/E and I am 5'6'' with bottom heavy breasts. This bra, while not the fanciest, is very comfortable and feels really silky-smooth on my skin. It is able to properly support my breasts and doesn't leaving gaping or wrinkles at the top like my other ill-fiting bras do.
I'm truly a 26DD, but Calvin Klein doesn't make 28 band sizes, so I got my sister size of 30C. It actually fits really well, the band is a little tight for a 30 and doesn't stretch too much. The underwire doesn't come up very far in the front which is good for me because otherwise it presses against my sternum. The lace at the top doesn't show very much through tight shirts, and doesn't itch! The bra is very comfortable and the cups give great support. The only problem for me would be that the top edge of the bra doesn't lay flat against my breast tissue, but i'm pretty sure that's more of a personal fit issue since i'm fuller on bottom. But this bra fits better than most others i've worn in that regard, so i'm not really going to dock off any points for that.
A great t-shirt bra. Medium-width wires, comfortable band, and easily-adjustable straps. Wasn't a good shape for me as it was too closed on the top. Would suit average-projection or slightly projected shapes better. Fit is pretty true to size.
The band on this bra is is too big for me but it was the best I had found so far. The shape doesn't fit quite right but it is still fairly comfortable except for the center gore being too wide. The bottom of the cup cuts in but the top of the cup gaps. This causes a line to show through certain shirts. The straps are too wide set for me but this is a common problem for me. The quality is good, durable, I have owned several of this or very similar model. (I usually wash them in the machine in a lingerie bag. Sometimes they go through the dryer too, oops.) The fabric is smooth inside and out. I have never had a problem with an underwire poking out of a channel. The fabric on the sides is lined but it is thin and has stretched oddly. I didn't care for the embedded cookies, they are not removable. If you prefer cookies then these are probably good because they are not going to move at all.
This bra gave me a similar shape as the Natori Feathers I tried. It's too shallow at the center, gives me a center quad boob, and pushes my tissue towards the sides. Not charming. It is very comfortable, so it's probably a great bra for some.
This bra is not the best for lower projected breast. But it works if that is all that you have. I owned 4 so did enjoy them until I found better fitting bras. Bra is just too small for me so I want to allow someone else to use it.
