A Princess/A-line is for you if:  You're petite, short or short-waisted. The vertical lines will elongate your figure. If you love your shoulders, go with a halterneck or off-the-shoulder design. To appear taller, choose detailing above the waist to draw the eye up.  You're full-breasted. Choose a scooped or V-shaped neckline in order to lengthen the neck. Avoid unsupportive spaghetti straps and plunging necklines that accentuate your cleavage.
