Sally has 1 sister.

Here is the step-by-step breakdown:

Identify the family members: Sally is a girl. She has 3 brothers.
Analyze the brothers' perspective: Each brother has 2 sisters.
Count the girls: Since the brothers are siblings, they share the same sisters. If a brother has 2 sisters, and one of them is Sally, there must be one other girl in the family.
Determine Sally's sisters: Sally does not count herself as her own sister. Therefore, she has the one other sister mentioned above.

Total:

Girls: 2 (Sally + 1 other)
Boys: 3
Sally's sisters: 1
