This is an interesting/fun thread. I'm almost 45 yrs old married with kids and reading your posts made me realize that I need to step up my game a little
When I'm traveling and depending on the climate, the clothes are usually comfortable (long yoga pants) with a couple cotton knit tanks and longer knit tops/sweater to layer so that I can take off as needed and it's not wrinkled upon waking up. I'm a classic minimalist so usually no makeup or very minimum (eyeliner/clear mascara). Just washing up etc and moisturizing helps tremendously. I love lotions etc but find that the Oil of Olay brand (old school) is just the right texture for my skin on the plane. Must haves: Chapstick, Clorox wipes (they sell in a travel pack size) to wipe down everything (screen, armrests, trays, buckles) and always have antibacterial wipes/gels on hand, plus my favorite scarf/pashmina and favorite plush socks.
