Leprosy In Clothes

When flowing garments I behold
Inspir'd with purple, pearl and gold,
I think no other, but I see
In them a glorious leprosy
That does infect and make the rent
More mortal in the vestiment.
As flowery vestures do descry
The wearer's rich immodesty:
So plain and simple clothes do show
Where virtue walks, not those that flow.
