Well, I know it broke rules about only one inch of midsection reveal, a slit only a few inches high (which is sort of technical but that hem is really high up, so), proper undergarments (she might have been wearing panties but no bra), and no see-through fabric over private parts (I'm assuming her nipples count, since the fabric on top seems fairly flimsy). It does say now that I look at it that bare back are acceptable, but I doubt undercleavage is okay.
