Job Interview Questions: Appropriate outfit for a job interview to work with children or homelessness?

I realize it depends on the organization, but I'm a recent college grad, applying to as many jobs as I can. I don't have time to visit all of them before an interview.
If I get an interview, should I wear a suit, or just dress pants and a button up blouse? Or something else? Honestly, I have no clue!
Note: this is East Coast, Virginia.

Job Interview Weaknesses - How to Overcome These Common Job Interview Weaknesses

Recommended Answer:
A suit is always appropriate for an interview, skirt suit or pants suit doesn't matter, as long as it fits well and is not provocative. Dress pants and a button up blouse is too casual for the interview. That may be what you wear to the job, but not to the interview. As for shoes, wear some that are safe and comfortable for walking in case you are taken on a tour of the facility.

Job Interview Help - Some Things That Might Help You Ace Your Job Interview

• dress pants and a button up blouse, but not TOO fancy. my mom owns a food bank in my town she HATES it when someone comes in for an interview wearing fancy things. you're trying to help the poor, why would you dress like your rich in fancy suits? and do you think children would wanna talk, play, and listen to you if you're wearing something so formal? cause if you wear something so formal to an interview, the people are gonna think "hey, she dresses like that all the time!" the human mind just works like that.
  
  i would really recommend wearing a dress shirt and leggings that go to your ankles, and cute sandals. dressy, but also casual.
  (it it seems sluttish to wear leggings under a shirt to you, wear jeggings)
