    A few usage guides still object to the use of comparison words such as more, most, nearly, almost, and rather with perfect on the grounds that perfect describes an absolute, yes-or-no condition that cannot logically be said to exist in varying degrees. The English language has never agreed to this limitation. Since its earliest use in the 13th century, perfect has, like almost all adjectives, been compared, first in the now obsolete forms perfecter and perfectest, and more recently with more, most, and similar comparison words:the most perfect arrangement of color and line imaginable.Perfect is compared in most of its general senses in all varieties of speech and writing. After all, one of the objectives of the writers of the U.S. Constitution was "to form a more perfect union.'' See also  complete, unique.

Etymology: 13th Century: from Latin perfectus, from perficere to perform, from per through + facere to do
For most of its meanings, the adjective perfect describes an absolute state, i.e. one that cannot be qualified; thus something is either perfect or not perfect, and cannot be more perfect or less perfect. However when perfect means excellent in all respects, a comparative can be used with it without absurdity: the next day the weather was even more perfect
