PBs are expected to be reasonably age-appropriate. This means they can pass as teenagers (who may look slightly older given the era), and do not look significantly older or younger than others in their year (refer to the castlist for examples). Models will not be accepted unless they have non-runway and couture icons.
PBs must be era-appropriate. This doesn't mean you need to go out and cap a WW2 era movie, but your PB should not be blatantly modern looking. The goal should be plain and conservative looking, to the best of your ability.
A list compiled by the lovely Ashley of pre-approved PBs (is here)
Examples of acceptable and not acceptable sets for modern PBs (credited beneath):
Every PB must have at least ten 100x100 icons of reasonable quality. Reasonable quality means that your icons are not skewed, too blurry, overly sharpened, cropped beyond recognition, or impossibly dark. We aren't icon nazis, we just want to see your pb!
Banned PBs -- please don't argue, mod discretion! Jensen Ackles, Gerard Butler, Megan Fox, Hannah Murray, Zachary Quinto, Ed Westwick, anyone who was in the Harry Potter movies as a notable cast member.
