Business class flight .... help! What do I wear - ideas gratefully appreciated!

[Millylovespuddles]

DH and are going on a special holiday to celebrate our 25th anniversary. So, we have splurged on business class flights en-route to Jamaica.

We go mid-Feb, and I'm having a sudden confidence crisis as I don't know what to wear..... I want to be comfortable, yet look stylish (and not look like an imposter)
I'm 55, 5'1, size 8 - feel youthful and want to look trendy, not trying.
Any tips? TIA

Are yoga pants just expensive leggings?

I would not be seen dead in pyjamas in a public place that was not a medical facility. How horribly intimate.

I splashed out on a cashmere cardigan once. I wore it several times but it did not confer instant chic. I was still fat and frizzy.

NOT PYJAMAS!

Hello! I came across this thread as I was wondering the same thing - so, in case anyone is wondering what the situation is in 2024 - I'm currently in the Club Europe lounge at Heathrow T5 for my first ever business class flight.

People are wearing all sorts! There are suits, but I guess they are travelling for work. Otherwise, a full mix of jeans, chinos, shorts, yoga leggings, trackies, dresses, etc - I'm wearing floaty black and white trousers and a black tshirt and definitely don't feel under-dressed. Just be comfortable and you will fit right in :-)
