I want to buy my lil sister a new pair of sunglasses, but I don’t know what would fit her. Do you know any kid sunglasses in a good price?

I am looking for a fabric that is durable, suitable for swimwear, will not fade in the sun in a hurry, offers the most comfortable fit, and stretches.. of course!

I want to buy an A&F bathing suit but am unsure of which size to get. I am a size 2 in their pants and an xsmall to a small in top (it depends). My bra size is 34C. I am unsure of which size to get. Has anyone ever bought their bathing suits? How do they fit?
