Whether you're planning some last-minute winter sun or already eyeing up next year's summer holiday, you might want to think twice about what you wear for the flight.
We all get it, it's nice to be comfy especially when flying long-haul or cramming yourself into the cheapest seat possible with your knees around your ears.
One flight attendant has revealed that one popular outfit in particular gives her the ick, so you might want to cross this one off your list.
They say you shouldn't judge a book by its cover, but this flight attendant in particular is absolutely judging you by your outfit.
And it's not just about covering up, either.

Flight attendant Cher Killough hails from Texas, and she's shared a TikTok about what your personal style tells her and her colleagues.
So, if you see the staff looking you up and down as you board, just know that an assumption is being made about you thanks to what you've chosen to wear that day.
She shared a video titled: "What I'm assuming about you based on the outfit that you're wearing on the plane, coming from a five-year flight attendant".
Be warned: she doesn't hold back, and your favourite fit might just be in here.
If you're a fan of Lululemon, Cher and her colleagues will be checking for a sizeable rock on your left hand.
She showed a Scuba top, saying the wearer is either 'a middle schooler' or dating someone with money.
Cher advises: "Ladies, if you're single, get you one of these, because I swear this girl always has a massive rock on her finger!"
The top retails between £84 to £108.
A sundress and sandals might seem like a sensible choice, but apparently it's a uniform for 'organic moms'.
The flight attendant insists the wearer is 'always a mom that has organic snacks in her bag - you know her pantry is always stocked and she's as crunchy as can be.'
Surely it's common knowledge not to wear a jumpsuit on a plane? After all, who wants to strip right down every time you need to use the facilities, as we all know how brutal air-con can be on board.
Cher says: "If you're wearing a lounge romper, I'm assuming that you did not think this through because that top is going to be on the pee-soaked floor of the lavatory."
Lovely, and so fragrant for your fellow passengers.
Super short shorts are also a big no, and not for the reason you might think.

Rather than for being risque, Cher says it's for hygiene concerns: "If you're wearing denim shorts or bike shorts, I'm assuming that you do not realize how many diapers get changed on those seats and you probably wouldn't care anyway."
Joggers are a popular choice for flying in comfort, but the style you opt for tells them a lot about you: "Wide-leg sweatpants are always accompanied by the Louis Vuitton Neverfull or the Goyard bag, and you very much are that girl," she advises.
If you prefer a more fitted style though, Cher says: "Cuff sweatpants, you just care about comfort, and that's okay!"
TikTok viewers rushed to the comment section to share their thoughts: "Pants and closed toe shoes ALWAYS," insisted one.
Another agreed with Cher's thoughts about the luxury life: "Wide leg sweatpants and I have a Goyard"
However, one style icon insisted you should go above and beyond: "I always get fully dressed. That aisle is a damn runway."
