Sorry to give you what is probably the epitome of a non-answer.
This is one of those specific to each person kind of things. If you think it is a good idea, then go for it. If not, then don't.
Personally, I think this would be up there with arriving at work, only to realize I forgot to put on pants. Embarrassing, to say the least.
I would give it some hard thought. Not just for your own sense of boundaries. But also because people tend to react to things like this in somewhat unpredictable ways. The people you think would be the most supportive, can sometimes do a total 180 when they see this for themselves.
Not saying that's what will happen. But being new to this ptsd thing, I'd suggest you take your time, weigh everything out carefully. There's no rushing this. Above all, make sure you are looking out for you, first and foremost.
At the end of the day, the most important person to your recovery, is you. Listen to your intuition, and be kind to yourself.
