YA Fashionistas: What ways can I make this summer top wearable in the fall?

Well, you could layer it up under a trendy blazer. Khaki, corduroy, or denim. Something that comes back every fall. Add either a cute mini (not in the same fabric as your jacket, though; looks too streamlined!) or a pair of jeans. With some trendy, eye-popping jewelry, (a great necklace will show off your collarbone in the strapless top!) you'll be set! Good luck. And by the way, cute shirt!
