ok the pink is lovely but you gotta have a tan to pull that color off so no on that one for you :\ sorry. Love the neon green though very cute! not a fan of the blue and white polka dot one and it's not actually blue it's a green color that's gonna make you look more pale.
I have two daughters with very pale skin like yours(one blond and one brunette) so I have a lot of practice at picking colors that look good on them. They look great in black and jeweltoned corals(neon coral even) and my blond daughter would look great in that neon green so I know it would work for you too.
Buy the one that you like the most, but I definitely would like to see neon green, because this is my favorite color :) I even painted my car into atomic green. It is light, happy, and super attractive.
The light pink design is much prettier than the other designs. However, I'm not sure how a light color will look on you if you say you are already very light skinned. Choose whichever color flatters you more but stick with that light pink swimsuit for sure. :)
I like the neon green! That's an awesome color choice I think, but its really what color you like best on yourself. And its not the push up kind that look like bras! that's a plus to me cause I personally couldn't wear one haha. Hope you find one you love!
