I just purchased this adorable drop waist dress on-line and personally found it to fit tts in my regular size small (34d-27-35). the length in the front hits right to the top of my knees, perhaps a tad longer so it's not too short for me (i'm only 5'4") and the back is longer in length. there is also a detachable matching cotton slip that snaps on or off the dress that has adjustable straps that hit just above my knees. i love that this dress was made from cotton and the color is just as picture
