Roxy by Quiksilver Bikini

Roxy Girl Bikini By Quiksilver Size 6X (we found this to fit closer to a typical 8, especially with the top) New with tags I would like to note that the solid purple sections look a bit sun faded or tie dyed. I honestly hadn’t noticed this until just now. I assume that’s how it’s meant to be? However I did buy this at Nordstrom Rack (price on tag was USD), so could be why it was there?
