The important points here are:
"to use these to pretend to be a member of the armed forces"
"as to be calculated to deceive"
"to falsely represent yourself as someone entitled to wear any such award"
Your red text appears to have come from a
BBC news report, but whoever originally extracted the text has done so rather selectively - they omitted the next paragraph, which clearly says
"Intention is all. Those, such as pop stars Cheryl Cole, Chris Martin and Sgt Pepper-era Beatles, who don military regalia for fashion would not be culpable."
Has TCT ever suggested that she was or had ever been in the RAF, or been trained/qualified by the RAF? I'm not aware of any such claim - quite the reverse since she has many published "CVs" which include no such claims. So there is clearly no Intent to deceive, and as such no offence.
