IMHO.......I have read a lot of iris publications and catalogs over a number of years and don't remember the term 'crimped' being used to describe iris flowers very often. Ruffled, gently ruffled, heavily ruffled, bubble ruffled, are used. Laced flower have tiny indentations which can be combined with ruffles. My personal taste is for lots of ruffles on wide nicely held petals as long as the flower opens well. I am not crazy for lace. Older iris, the historicals, I would call tailored or perhaps plain.
