I'm 5'5" and the dress was short.
After many washings, my dress (SIze L) measures about 32 1/2 from center of neckline to the hemline. I am 5'4 1/2 and it hits me just above the knee. (consistent w photo) I wear it with tights but it is definitely dress length on me. Maybe someone taller would be consider this a tunic, but I am very comfortable wearing this as a dress. Hope this helps.
33" is correct.
