For the not so brave select the Maxi dress or a frock safely just on the knee.  Maxi dresses and skirts were popular daytime alternatives to short looks and hot pants in the 1970s.

Flamenco ruffles, flounces and frill are visible on many garments from blouses to skirts, as are accordion pleated frills like Fortuny pleating.  Many of these maxi dresses have a final frill at the lower hemline. 

Flounces created by elastication and drawstrings are also evident on folkloric dresses especially at shoulders.  Long tunic or mini dress gypsy tops with elastication that can be pulled on and off the shoulders with ease will enable you to customise your own fashionable look.

Again don't be afraid to ignore any of these lengths and find a length that flatters your body and your legs.  You have to feel comfortable and once you find a shorter length that is just so for you, then you are more likely to wear it with confidence.
