I know this is old news, but it'll be bathing suit season again before we know it, and I'm majorly crushing on Miranda's retro red bathing suit from the Mexican vacation the ladies took in the SATC movie. Every time I watch the movie, I drool over it, then laugh at the waxing scene that follows. Miranda's actual suit retails for hundreds of dollars, but I've found three great looks for less that, while not identical, do a pretty good job of portraying the retro red vibe of Miranda's swimsuit.
Both 1 and 2 are from Victoria's Secret. At over $100, they're still pricey, but they're also high quality suits that will hold in your wobbly bits and give you good support. Number 3 is from Urban Outfitters and retails for $98.
None of the suits are totally cheap, but then again, when it comes to something you'll wear on the beach, you've got to look good!
