Classic Poem

I've often made clothes
For those who write prose,
But 'tis the first time
I've had orders in rhyme—.
Depend on't, fair Maid,
You shall be obeyed;
Your garment of black
Shall sit close to your back,
And in every part
I'll exert all my art;
It shall be the neatest,
And eke the completest
That ever was seen—
Or my name is not Green!
