The Truly Victorian 1880's Corset Pattern is a great starter corset pattern. The simple lines make it fairly easy sewing, however the instructions are not thorough so you need to have some understanding of corset construction or a stong sewing background for this project to go smoothly.
Materials are always hard to estimate for a corset since altering the pattern in length effects the length of bones and busk required. It's always best to make a mock-up to determin fit and length alterations needed BEFORE ordering supplies.
The pattern envelope suggests:
Busk 1 (based on the pattern it looks like a 14" would fit)
6m corset lacing
1-2 packages of extra wide double fold bias tape (6 meters or yards)
12-28 steel bones - lengths are not listed
