I bought this dress for my mom to wear as a SURPRISE for their 50th Wedding Anniversary! Her and I are about the same size, I'm 150 lbs, and I'm 5 ft tall, 36DD. I ordered the medium and the large just to make sure to get the right size. The medium fit well, but the arms on the sleeves were just a tiny bit tight and would work if you like it to fit more to your body. My mom hates anything tight on her arms or her tummy, so the Large is what i went with to give a little bit looser fit. She is all of 4'10 though so I had to have it hemmed to fit her. The other reviews are correct about the bottom material on the dress being a little see through but a slip would work, but since I had to have the hem altered I just had the tailor add some material to the bottom. She thought it was a $200-300 dress and was flabbergasted when I told her I got it on Amazon for such a good price! She said she was very confidant and comfortable in it and loved the fit. The sparkle on this dress just can't be justified with pictures, in person it looks amazing and my mom looked absolutely beautiful in it!! So happy with this purchase!
