Im 5 foot 4 inches, 128lbs and wore this dress for a black tie event last night. It fit "like a glove" however, it was short. As you can see, Im not tall and with 3 or 4 inch heels, its too short, I had to downgrade my heel length to a 2.5 inch heel so it would look right. Otherwise the dress looked amazing and I received a lot of complements. If you are 5,4 and want to wear 3 inch or taller heels, order the 4L. I didnt wear any panty hose or undergarments as the dress had a built in bra that was just enough support for me. I highly recommend this dress.
