Petticoats and Crinolines in every color under the sun. http://www.PettiCoatStyle.com How do I measure for a petticoat / crinoline? What length to order? Depends on the dress and your height. Put the dress or skirt on. Measure down from naval to bottom of where dress / or skirt hem is. Your petticoat needs to be about that length or 1" longer for more peek out of the petticoat. What about my waist measurement? Measure yourself at the naval with a bit of snugness on the tape measure. That is your number!
