2 years ago I got this plant as a bonus from a grower who was going out of business. This is the first bloom. The marker has vanished. I presume it is either Advanced Degree or Ice Cream Sundae - both are pale, and laced but this iris doesn't actually look like either of the plants' pictures in the database. I know @AndreaD has Advanced Degree and @evelyninthegarden has Ice Cream Sundae. So if this isn't either of those, I have no idea what it is. Help appreciated.
Name: Marilyn, aka "Poly" South San Francisco Bay Area (Zone 9b) "The mountains are calling..."
I also have ADVANCED DEGREE, and this does not appear to be it. The standards should be more orchid or lavender, and the beard on mine is a stronger orange.
Sorry I can't be of more help.
Evaluating an iris seedling, hopefully for rebloom
