Price should not be a factor because Canon Law states, “Religious are to wear the habit of the Institute made according to the norm of proper law as a sign of their consecration and as a testimony of poverty” (Can. 669 section §1). It implies that all religious should wear a habit and all Institutes should adopt one. The Dominicans of Nashville and Ann Arbor, which have hundreds of teaching sisters make their own habits and wear them much, much longer than two years. Think more like ten. It’s okay to adapt the habit to the times, for example, the Daughters of St. Paul. However, I believe the full habit entails the perfection of modesty, so I have greater esteem for the orders that bind themselves to that.
