Apparently the airline has a policy against travelling in underwear, which seems reasonable. But that’s not underwear. Maybe they thought it was? But the whole shitey way it was handled suggests it’s just bellendry
Purely personally, as far as “look at me” goes I don’t think it’s really a fair comment. I mean, yeah a lot of clothes choice is about how you look, dur, but I don’t see anything that’s shouty or outrageous or particularly attention seeking, it’s really within the spec of Just Wearing Clothes.
(and besides, thinking with my knob for a second if she’s trying to say “look at me” she’s essentially drawing attention away from a rather lovely and characterful face towards a less noteworthy frontage. I can’t say I’d go phwoar or pay her more attention than I would if she was more covered up, she is attractive for the full package and especially for the wee nearly-smile not for the bits she’s “showing off”. I think that top + huge breasts could well be very shouty but this isn’t)
