They were both forms of stiffened supports for the rear of 
skirts.  By 1869 the flounce frilled horsehair tournure 
dress improver or bustle was the undergarment to own to 
achieve the fashionable silhouette of the day

False undersleeves were called engageantes. Woman could 
emphasize modesty by wearing freshly laundered detachable 
white collars and false undersleeves. These were often made 
of delicate whitework and gave an air of refinement and 
daintiness.

In the Victorian era a widow would mourn for two and a half 
years, with the first year and a day in full mourning.  
During that time pieces of the crape covered just about all 
of a garment at deepest mourning, but the crape was 
partially removed to reach the period of secondary mourning 
which lasted nine months.  After that the crape was defunct 
and a widow could wear fancier lusher fabrics or fabric 
trims made from black velvets and silk and have them 
adorned with jet trimming, lace, fringe and ribbons.  In 
the final six months a period called half mourning began.  
Ordinary clothes could be worn in acceptable subdued shades 
of grey, white or purple, violet, pansy, heliotrope, soft 
mauves and of course black.

Crape for mourning. Crape (always spelt with an ?a? to 
indicate mourning crape) was the most used fabric for 
mourning clothes.   Crape was dull looking silk gauze like 
a crimped and stiff textured material and mostly dyed the 
deepest of blacks, although white crape was used for the 
widow's cap.  Black was the chief mourning colour in the 
immediate months after a death for deepest mourning.

Crin' is French for horsehair so the word crinoline 
suggesting a crin lining was used for any garment area that 
was stiffened to give shaped foundation. Strip hem linings 
and a sleeve head are just two examples where crin was 
used. Later by 1850 the word crinoline began to mean the 
whole of the beehive shaped skirt. It was then only another 
step to call the later artificial or cage hooped support 
frame petticoats after 1856, crinolines.

The Cage Crinoline or Artificial Crinoline was invented in 
1856.

Queen Victoria wore widow?s weeds until 1901.

A Coal Scuttle was a fashionable Victorian bonnet style

In England Teddy Boys or Neo-Edwardians sported long low 
thigh or to knee jackets with narrow contrasting lapels and 
matching contrast drainpipe trousers. Their hair was 
slicked back into a  style with long sideburns. They wore 
crepe soled shoes which helped with the dance movements of 
jiving. Their girlfriends wore eye make up and took every 
fashion to excess.
