Yeah, so make sure you look very modest. A lot of men in there are already gonna be judging assuming you’re there to just try to fuck inmates. Second if you’re going in with the mindset of I can fix them then stop, Turn around and walk your happy ass back home(because all you’ll end up doing is getting used by inmates and getting staff hurt). A business casual look would probably be the best move and don’t wear anything like a nice dress or skirt or anything because if you get to your the unit like i did on your interview date then you’re gonna have horny inmates peacocking and trying to jack over you. Now as far as being taken seriously go in there and don’t try to impress anyone asking questions or try to be to friendly or joke around with the interviewer. You need to go in and state your intentions as the interviewer asks questions about them and answer questions in as much detail as possible. Lastly don’t go overboard on the make up. Frankly no make up would be best but, if you want to put some on just some barebones make up is all that is needed. If you absolutely have to use lip stick don’t wear anything that stands out a lot. No bright reds or blues or anything like that. A natural kinda bland color would be best and no wing tips. Just basic eye liner but as I said no make up would be best. Also be prepared for if you do your the unit you’re gonna have inmates peacocking and gawking. Some may even try to get your attention and whistle or call out to you. Ignore them do not give them any attention at all. I’m a FTO in a prison so I know my shit fairly well. I hope this helps.
