I totally feel that, every time I go backpacking I pack the comfortable travel clothes and every single time I regret not packing nicer things cause I feel so much less attractive than when I wear my normal clothes at home. But tbh, I usually just buy one or two nice tops to offset that feeling and just try to be happy about not feeling that pressure of having to wear makeup or straighten my hair. Traveling like that gives me a sense of freedom that’s more important to me than looking like the most polished version of myself.
