elaborate ornamentation imitated from Greek and Roman examples or containing
classical allusions, as animal forms for the legs of furniture, bas-reliefs of
classical figures, motifs of wreaths, torches, caryatids, lyres, and urns and

1250–1300:
From the Middle English empire (territory subject to an emperor's rule (and, in general "realm, dominion"), from
the Anglo-French & Old French empire
& empere (rule, authority,
kingdom, imperial rule; authority of an emperor, supreme power in governing; imperial power), from the Latin imperium
& inperium (a rule, a command;
authority, control, power; supreme power, sole dominion; military authority; a
dominion, realm) from inperare & imperāre (to command) from parāre (to prepare; to make ready; order). The construct of the Latin imperare was in- (in) (from the primitive Indo-European root en (in)) + parare (to order, prepare) (from the primitive Indo-European root pere- (to produce, procure). A doublet of empery and imperium.
In English, the early understanding of the word was defined substantially by the knowledge (however imperfect) of the Persian and Roman (especially the latter) empires of Antiquity and though never etymologically restricted to "territory ruled by an emperor", for entirely logical reasons it did tend to be used that way. The phrase "the Empire" (which in the UK and the British empire almost exclusively implied "the British Empire" (dating from 1772)) previously would have been supposed to be a reference to the Holy Roman Empire. Officially, the British Empire devolved into "The Commonwealth" in 1931 because of the constitutional implications of the Statute of Westminster (and the changing world view) but opinion is divided on when it really ended, most dating it from Indian independence in 1947 (when George VI ceased to be George RI (Rex Imperator (king-emperor)) and became George R) while others claim (less plausibly) that in a sense it endured until Hong Kong was handed back to China in 1997. Nobody claims that still holding the Falkland Islands an empire makes.

Always a civilizing project, the Roman Empire stopped short of Ireland and Scotland. One has to draw the line somewhere.Despite
the modern habit, etymologically, empire was never restricted to
"territory ruled by an emperor" but has been used that way for so
long a meaning-shift may have happened.
In political theory, an empire is an aggregate of conquered, colonized,
or confederated states, each with its own government subordinate or tributary
to that of the empire as a whole but history is replete with accidents and
anomalies. Japan’s head of state is an
emperor although no empire exists and the most often quoted remark about the Holy
Roman Empire has long been Voltaire’s bon mot that it was "...not holy, nor
Roman, nor an empire".
Long
pre-dating the era, the empire-line (sometimes called empire-silhouette) dress is
most associated with the French First Empire (which lasted from 1804 when
Napoleon Bonaparte crowned himself Emperor, to his final defeat at the Battle
of Waterloo in 1815) and although the look endured longer than the political
construct, beginning in the 1820s, skirts widened and waistlines lowered to an
extent most were no longer identifiable as the style. The look became linked to the First Empire
because it was Napoleon's first Empress, Joséphine de Beauharnais (1763–1814) who
popularized it in Europe and there are fashionistas who when speaking of the
style, will pronounce it as a quasi-French om-pire. In England, Emma, Lady Hamilton's ((1765–1815);
mistress of Lord Nelson (1758-1805) and muse of the artist George Romney (1734-1802)) adoption of the
style was much imitated, the cross-channel exchanges of fashion continuing
uninterrupted even when a state of war existed between London and Paris. The English or American fashions of this time
tend respectively to be termed "Regency" (referring to the Regency of
the Prince of Wales, 1811-1820) and "Federal" (referring to the
decades immediately following the American Revolution).

Empire-line
dresses featured a waistline considerably raised above the natural level with
skirts which vary from the slim and columnar to the swishy and conical. In its pure form it was characterized by (1)
a columnar silhouette without gathers in front, (2) some fullness over the
hips, (3) a concentration of gathers aligned with a wide centre-back bodice
panel and (4), a raised waistline which reached usually to just below the bust
but (occasionally) as high as the armpits.
Mass-production of the design was possible only because the industrial
revolution made available new fabrics and other materials at volume and an
attainable cost. Empire- line proved
appealing to women without an ideal figure because, by adjusting the parameters
of the various components, a seamstress could flatter a wide variety of body
types, disguising and emphasizing as required, able to create also the illusion
of greater height.

The empire-line inherently needs a lot of fabric which offers designers the possibility of using bold patterns, especially florals, which can't be displayed to the same effect in styles with less surface area.Traditionally,
most clothing had relied on the shape of the human body but new forms of
corsetry, including strong yet delicate shoulder straps to provide the
necessary structural integrity, combined with materials such as mull, a soft, sheer Indian white muslin, allowed
designers to create wearable outfits in which the neoclassical influence was
obvious, the silhouette imitating the Classical statutes of Antiquity. Such constructions had before existed for the
rich but they were heavy, hot, rigid, uncomfortable and very expensive. Sadly,
the relative freedom women enjoyed proved short lived, evolving by the 1820s
into something less simple and notably more restrictive, the hourglass
Victorian styles much more prevalent in high-fashion by the mid-nineteenth
century, a trend which lasted until the First World War. The ideas of empire-line were revived for the
less-constricting clothing popular in the 1920s and, although coming and going,
it’s never gone away and, being somewhat hippie in its look, gained a new
following in the 1960s.

Although the design and structural details differ between these, all four can be reduced to the same mathematics. The wedding dress business seems to be one part of the industry where blonde models seem not to enjoy their usual natural advantage, photographers preferring dark hair, better to contrast and define the edges of all that white fabric.

Today, empire-line dresses are still often worn and the style gained a new audience from their used in the Mad Men television series, set in upper-middle class US society during the 1960s. One place where they've long inhabited a stable niche has been the Western wedding dress where the technical aspects of the design, the fitted bodice, high waist, and loose-fitting skirt allow the creation of silhouette that’s flattering and forgiving for a wide range of body shapes, once a genuine selling feature for brides with child who, in less accepting times, wished to conceal the bump. However, even though the empire- line is almost uniquely ideal at shifting focus from the waistline, it can be cut in a way to complement the slender, delivering a cinched waist. In either case, the same mathematics are at work, the goal being to elongate and define and by creating the visual effect of the narrowest point appearing just under the bust, it can either (1) trick viewers into seeing a longer torso, diverting attention from the midriff and hips or (2) emphasise the waistline of the truly slender, making it perfect also for the petite or short.
