Olalla Oliveros. Make-up did a lot. I recall an article
concerning her conversion at Fatima when she said she was
thinking of becoming a nun - I can't find the piece right now.
Keep it simple and stay off television talent shows after final vows.
Somewhere - I think it may have been in Seven Story Mountain that Thomas Merton wrote that one of his greatest penances was living with men devoid of any taste. That's not an exact quote, but it captures the sentiment. Look around at any ordinary parish - check out the environment, the vestments, the women religious in capri pants and t-shirts.
Even new religious communities, though more traditional, demonstrate a surprising lack of aesthetic sensibility - especially when it comes to the design and coloration of religious habits. Olalla Oliveros' community of St. Michael the Archangel adopted a strange habit. The coloration and insignia seems a bit Disney to me. The male branch of the order wears the same habit.
To each his own. I expect there must be some spiritual significance to the variety, but plain, no color strikes me as the best and most modest choice for religious - but who am I to judge? I've always said I could never be a priest or religious because I never liked the clothes. Perhaps today Olalla Oloveros' greatest penance is the clothes.
Just for fun, a few unusual habits for view... (I'll update as I come across more.)
Not so bad - the blue is kind of intense though.
A little blueish.
North American classic.
