The prints are adorable, the straps are adjustable and they'd look great with a pair of denim capris. You can dress the tops up or down (a strand of pearls around your neck can do wonders).
Victoria's Secret often has lingerie that can double as groovy outdoor-wear. Check out that section of the site from time to time--you'll be surprised.
The best part about these camis? They're on sale for $16! Yippee!
