Overfrock: An over-frock coat is an overcoat designed to be worn over a frock coat as an overcoat in cold weather.  A top-frock coat is also worn over a frock coat in milder weather.  Shaped like the body coats popular in the late Victorian and Edwardian periods, the over-frock coat was cut in essentially the same way as the frock coat that was worn under it, although it would be larger overall to accommodate the frock-coat worn underneath.  Like the frock coat, the over-frock would be single-breasted, with step lapels for informal occasions, like business, and double-breasted, with pointed lapels for formal occasions - weddings, funerals, balls, &c.  The formal variety was known as a 'Prince Albert' overcoat.  A frock-overcoat, like a frock coat, almost never has pockets.

Bluecoat school: A Bluecoat school is a type of charity school, the first of which was founded in the 16th century.  Most of these have closed, some remain open as schools, often on different sites, and some of the original buildings have been adapted for other purposes.  They are known as "bluecoat schools" because of the distinctive blue uniform originally worn by the pupils.  The colour blue was traditionally the colour of charity, and was a common colour for clothing at the time.  The uniform included a blue frock coat, and yellow stockings with white bands.

Scrooge McDuck: Scrooge McDuck is a fictional character created in 1947 by Carl Barks during his time as a work-for-hire for The Walt Disney Company.

Duffel coat: A duffel coat, or duffle coat (standard UK spelling), is a coat made from duffel, a coarse, thick, woollen material.  The name derives from Duffel, a town in the province of Antwerp in Belgium where the material originated.  Duffel bags were originally made from the same material.  The duffel coat may have initially come from the Polish military frock coat, which was developed in the 1820s.  The hood and toggle fastenings proved popular and it spread across Europe by the 1850s.  By 1890 it was being supplied to the British Royal Navy, and Field Marshal Montgomery was a famous wearer of the coat in World War II.  After the war, the coats became available as government surplus stock and became popular, especially with students.

Frock coat: A frock coat is a man's coat characterised by a knee-length skirt (often cut just above the knee) all around the base, popular during the Victorian and Edwardian periods.  The double-breasted style is sometimes called a Prince Albert (after the consort to Queen Victoria).  The frock coat is a fitted, long-sleeved coat with a centre vent at the back, and some features unusual in post-Victorian dress.  These include the reverse collar and lapels, where the outer edge of the lapel is cut from a separate piece of cloth from the main body, and also a high degree of waist suppression, where the coat's diameter round the waist is much less than round the chest.  This is achieved by a high horizontal waist seam with side bodies, which are extra panels of fabric above the waist used to pull in the naturally cylindrical drape.
