Almost seven years ago, I was given the gift of a pale blue teeshirt similar to the purple one in the photo above.
I have worn it on and off during that time, mostly outside of church contexts, and with varying responses. I was once told it was an 'aggressive statement' to wear such a teeshirt; more often people have smiled and among non-church people it can be a good conversation starter.
Because my blue one is just about worn out, and because the organisation supporting US women Baptist ministers needs some support from this side of the pond (imo), I've just ordered a new purple one.
I will look forward to it arriving - and to deciding what are suitable occasions for it to make an appearance!
PS they are available for men also!
