I was just thinking how times have changed...when I was a kid and we used to travel, everyone was so formally dressed (looking their best) probably because it was a big deal back then as international travel was not that common, now its a lot of casual wear, sometimes socks & crocs -

I always bring a sweater because the ac is most likely on arctic blast and the thin blankets offer little warmth, I also wear comfortable shoes and drink lots of water to stay hydrated 💚
