Sometime in the late 17th or early 18th century the small kilt (, anglicised as
filibeg or
philabeg), using a single width of cloth worn hanging down below the belt came into use, becoming popular throughout the Highlands and northern Lowlands by 1746, although the great kilt or belted plaid continued to be worn. The small kilt is a development from the great kilt, being essentially its bottom half. The tailored kilt was adopted by the
Highland regiments of the British Army, and the military kilt and its formalised accessories passed into civilian usage during the early 19th century and have remained popular ever since. A regimental kilt of the
Gordon Highlanders (92nd Regiment of Foot) from c. 1817 still survives in remarkable condition at the
National Army Museum.
Dispute about invention , c. 1747, in a belted plaid with a retainer in the small kilt, probably the first to appear in a portrait. A letter written by Ivan Baillie in 1768 and published in the
Edinburgh Magazine in March 1785 states that the garment people would recognize as a kilt today was invented in the 1720s by
Thomas Rawlinson, a
Quaker from
Lancashire. After the Jacobite campaign of 1715, the government opened the Highlands to outside exploitation, and Rawlinson went into partnership with Ian MacDonnell, chief of the
MacDonnells of Glengarry, to manufacture charcoal from the forests near Inverness and smelt iron ore there. So the story goes, the belted plaid worn by the Highlanders he employed was too "cumbrous and unwieldy" for this work, so, together with the tailor of the regiment stationed at Inverness, Rawlinson produced a kilt which consisted of the lower half of the belted plaid worn as a "distinct garment with pleats already sewn". He wore it himself, as did his business partner, whose clansmen then followed suit. Maj. H. R. Duff (1815) repeated the story, in short form, as fact in his
Culloden Papers, and Sir
Walter Scott (1816) agreed with him in a review of the book.
David Stewart of Garth (1825) wrote of the story as being unsubstantiated, and "one of the arguments brought forward by some modern authors, to prove that the Highland garb is of recent introduction." Some 19th-century writers supported the notion of the story but did not get the details correct:
John MacCulloch (1824) remembered the name "Rawlinson", but placed the events at a lead mine in
Tyndrum, while
John Sinclair (1830) wrote "it is well known that the phillibeg was invented by an Englishman", but then got the location and date wrong. A 1914 article in
Celtic Review considered that the story not appearing until half a century after the alleged invention was suspicious. Reactions of 20th- and 21st-century researchers to the Rawlinson story have been mixed. J. G. Mackay (1924) calls it a "myth" without "credence", but one difficult to dispel for having gone so long without "a serious attempt to contradict it". He suspects a military-politics motivation behind the letter: "There was at that time, as on several occasions since, an attempt being made to have the wearing of the [Highland] dress by the Highland regiments discontinued ... and the article in question was written with the intention of discrediting the dress as a national garb." Sir
Thomas Innes of Learney (1939/1971) calls it a "wretched story". Barnes & Kennedy (1956) say the idea "was attributed" to Rawlinson, without taking a side. John Telfer Dunbar (1979) takes the letter at face value, and
Hugh Trevor-Roper (1983) accepts it without much question, relying on it heavily in a later posthumous volume (2008).
Banks & de La Chapelle (2007) label the story a "legend", accept the location, then suggest that the workers themselves may have invented the short kilt.
Murray Pittock (2010) wrote that "it is ... ridiculous to suppose that an English Quaker industrialist could determine the sartorial priorities of ... a national culture" and that the story was characterised by "easy vehemence and lack of either rigour or depth". John Purser (2020) reports that there is no evidence to support the story in Rawlinson's own copious detailed papers. It has been suggested by Matthew Newsome (2000) that there is evidence of Highlanders wearing only the bottom part of the belted plaid before this, as early as the 1690s. and Dunbar argues against his interpretations. Mackay further suggests Scottish coats of arms published in 1659 and 1673 show
supporters in small kilts, and A. Campbell (1899) did likewise, as did Innes of Learney; Dunbar again offered a conflicting opinion. Mackay also quoted c. 1715
Scots Jacobite songs that specifically mentioned the "philabeg", and mid-17th-century sources that seem to treat the plaid and kilt as separate garments. J. F. Campbell (1862) also pointed out such material. A similar passage appears in
William Brereton's
Travels, written 1634–35. A 1677 account by one Thomas Kirk of Yorkshire described Scotsmen wearing "a sort of breeches, not unlike a petticoat, that reaches not so low, by far, as their knees. ... with a plaid over the left shoulder and under the right arm ...." Dunbar, relying on H. F. McClintock (1943), argues that it is not clear that the "petticoat" and plaid were separate garments (i.e., that the entire getup could have been a belted plaid). Dunbar called it "an ambiguous reference" that has been "furiously" debated. Mackay raised a point of logic: Since the belted plaid was made of two pieces of tartan cloth stitched together to provide the necessary top-to-bottom span, "It is surely too great a strain upon our credulity to ask us to believe" that no one before Rawlinson ever thought to use the lower one by itself. J.-A. Henderson (2000) accepts the historical visual evidence: "The idea of making the [belted] plaid shorter probably occurred to several people, as a smattering of early pictures show"; but he considers Rawlinson to have popularised the idea. All of the above is typical of the long-running debate, with different authors (often with unkind words for the opposition) offering their opinions and some evidence, with neither viewpoint clearly having the evidentiary upper-hand. Professor and museum curator Hugh Cheape wrote of the dispute: "Such a debate has tended to be circular, without adding much more than value judgement to our knowledge of Highland dress." Nonetheless, the kilt of Rawlinson's factory is the earliest documented example with
sewn-in pleats, a distinctive feature of the kilt worn today. Probably
the earliest portrait unambiguously featuring a small kilt is one of
Alastair Ruadh MacDonnell of Glengarry (in a belted plaid and tartan jacket), son of the aforementioned Ian MacDonnell, with a retainer in the background in the small kilt. The artist is unknown, and the painting is loosely dated to c. 1747. Dunbar argued that the location of Glengarry supported the idea of the small kilt originating there. ==Proscription and revival of the kilt==
