Vintage Oscar De la Renta Bodysuit, size 10 swim

I purchased this when traveling in Thailand, it appeared to be older vintage and did not show signs of being worn previously. I wore it swimming one time and the colors bled onto my white dress. This was surprising! Also, when wet, my nipples shown through!!! SO, I am questioning if it is meant to be a swim or bodysuit. Knowing what I know now, I am going to style it with a high waisted midi-skirt or some dramatic wide legged pants and not swim in it. Made in the USA Nylon and Spandex
