Until the 1920s wedding dresses were always in the "style of the moment", she added, if more elaborately decorated than usual and more modest than the most daring fashion. Hemlines for ordinary wear rose from the shoe to well above the knee.
At first wedding styles followed suit, and brides showed their ankles, but as skirts became ever shorter some felt them to be unsuitable for a church service, and brides tended to prefer full-length gowns.
After the Second World War, when clothes and fabrics were rationed, uniforms were ubiquitous and frivolity was frowned upon. Fashion came back; everyone was keen to wear long gowns on their wedding day made from luxurious fabrics.
The earliest gown to be exhibited, now 138 years old, was made of blue figured silk trimmed with dark blue braiding.
"It would have been high London fashion in the 1870s," Mrs Ramsey said, "but it is very fragile, so will be displayed in a manner that protects it from any further damage."
The other gowns to be shown, all part of the museum's fabric collection, range from 1904 to 1947, a 1947 flower girl's dress completing the lineup.
They will include the gowns worn by Selena Skelton, who married Alfred Ward in 1879, by Florence Crene, who married Sydney Puckey in 1904, by Mary Silva, who married Alfred Maddox in 1921, and by Peggy Miller, who married Leonard Keene in 1922.
The first two will only be displayed for a short time, in rotation with each other, as their age and fragility make them vulnerable to damage by lighting.
Mrs Ramsey said the museum staff were excited about staging the display, and were hoping for strong public interest at Saturday's opening (2pm).
"We promise you a piece of the wedding cake," she said.
"We are also asking that you dress formally for this special occasion.
"If you are able to wear your own wedding gown, or dress as the mother of the bride or bridegroom, in outfits that have been worn at a wedding, that would be splendid."
