What should I wear on this flight?

This Friday I'm flying 15 hours to Tanzania from New York, changing planes in Amsterdam. Obviously I want to be comfortable, but I'm flying with National Geographic and a group of high school kids I will meet in person for the first time at the airport Friday. I'm a high school student by the way. I don't want to show up looking sloppy, but I want to be comfortable for such a long travel.What should I wear on this flight?
you should buy some new sweats that fit correctly and aren't baggy. i have flown from california to ethiopia and trust me, you get uncomfortable wearing loose clothing because you're sitting so long, let alone a tight top and jeans!What should I wear on this flight?
Just try to wear some loose and comfortable clothes, and bring a jacket in case the plane gets cold. I usually wear sweat pants and a loosely fitting t-shirt with a hoodie and tennis shoes. It's not really worth it trying to wear something fabulous because after a 15 hour flight, it probably wouldn't be as fabulous as it started out as.What should I wear on this flight?
Options:

- Long or ''maxi'' dress with a jacket and cardigan just in case, you can carry it or put it in your carry on if you need it. They are comfortable and you wouldn't look ''sloppy'' you could also wear flip flops or gladiators with them.



- Floral skirt, They flow and are comfy. You can match them with anything because they usually have patterns on the bottom, and you can wear a solid v-neck or tank tucked under it, with any shoes.



- What ever you do decide to wear, make sure you stay comfy and warm! It doesn't matter that much, don't over think anything! Wear something you might wear to the movies or something, but it's just a flight.

- Or you could wear some shorts, and a shirt (or whatever) and change into something comfy (sweats, PJs, ect.) on the plane, and then change back when you get ready to land. A lot of people do it.
