Famous quotes containing the word doublet:

I find the laurel also bears a thorn.”

“Lord Hamlet, with his doublet all unbraced,
No hat upon his head, his stockings fouled,
Ungartered, and down-gyved to his ankle,
Pale as his shirt, his knees knocking each other,
And with a look so piteous in purport
As if he had been loosed out of hell
To speak of horrors.”
—William Shakespeare (1564–1616)
“Dost thou think, though I am caparisoned like a man, I have
a doublet and hose in my disposition?”
—William Shakespeare (1564–1616)
