My favorite t-shirt EVER!
Color: White, Size: Medium
This is the classiest t-shirt i have ever owned. It is buttery soft but thick so that nothing shows through. Thick doesn't explain it well because it is like silk on your skin. Anyway, I highly recommend such a lovely shirt!

Great fit
Size: 38DDD, Color: French Blue Lace
I first ordered this bra about 3 years ago. You know how us woman are we have more than one bra and more than one style of bra. This one style is the one I mostly reached out for. Then I went and lost around 45 pounds and it just didn't fit right any more. I went to to one of those "Bra Stores" and tried on a bunch of different bras none felt like it fit right so I came home and "measured" myself and I ordered a pretty blue one from comfort choice. My old bra was a 42G my new size is 38DDD. It fit so well I ordered 2 more. Light grey and pretty pink. I love these they are very comfortable and they hold the girls in place! Me I'm 67 5'3" and 165lbs.

Nice support but...
Size: 42DDD, Color: Black
I ordered this for my cousin who finds it very difficult to find bras in her size. She told me she wished she could find a good support bra without the wire because she had deep red marks under her old bra so I did some research and found this bra. She came over and tried it on and my first impression was WOW the support is great but it was very difficult for her to fasten all the hooks in the front due to her long nails. After some time she managed to fasten all the hooks and I noticed I needed to adjust the straps for her and she said it felt a lot better. This wireless bra looks so different on a woman with large breasts than the models in the picture, my cousin's cleavage was very substantial, unlike the model in the pic so if you are heavy set with large breasts, just know you will still have ample cleavage showing. After she put her top back on I noticed just how smooth her back looked, there were no bulges showing and she told me she felt like her posture was better due to the support of this bra. I have four stars due to the hooks being difficult to fasten.
