Suntan pantyhose make legs look like their suntan?

yes I'm a 18 yrs old girl and i wear them for the first few days when i go abroad on holiday. i get a tan through them eventually so i don't look too white. i leave them on all the time for the first week i even wear them under my shorts for swimming. people sometimes comment when they see me sunbathing or swimming in pantyhose but it doesn't bother me i am a girl so whats so strange?
