Why am I seeing so many color blocked swim suits?

I was searching for a swim suit the other day, and I noticed a lot of color blocked swim suits in one and two piece. Color blocking seems to come in and out of style every few years. I have to buy a new suit every year because my body changes so. I don't mind investing in a color blocked suit or two for a year if this is going to be "the thing" this summer. I have a long torso, so I wonder if they have any tankinis in color blocked?
