I would definitely try popping into local shops like Target, Old Navy, and H&M for super-affordable options. If you don't tend to have any fit issues, you can easily get away with something on the lower end, but consider going for a slightly pricier option like this Esther Williams suit that comes in a wide range of sizes and is universally flattering.
