to make it simple, i think there should be one What are you wearing today thread which includes which should include the 'you and your ironhearts', 'WAYWT IH', and 'what are you wearing/doing with your clothes today'
I think if we really want to best utilize a 'fit pics' thread, we should make it such that it is the one-stop to asking about an iron heart item, lets say IHSH-20, and then wait for someone to help out with sizing, be it giles or any of the other forum members.
These are my quick 2 cents, lets do this.
