Arguably the most important part in corset making is to determine your size before plotting anything out or choosing the corset pattern to use. A good pattern will have many size markings on it with most patterns ranging from 6-26. Most of the patterns available usually have an allowance of two inches of ease at the back for lacing up your outfit. Therefore you should not be worried if the pattern seems to be small according to your size.
You should find your size by taking waist, bust and hip measurements. After determining your correct size, you can now comfortably cut the pattern out. Put a tape measure across the t section of your bust while sporting a bra that is typical to your bust measurement.
Locate your waist measurement by wrapping a tape measure around the thinnest element of your waist, 2″ (5 cm) above the navel. The corset can be a clothing worn to shape the body. Usually, you’ll take 4 inches (10-cm) away from the waistline measurement. The top-hip measurement is made by covering a tape measure around the section of your hips. This can be around 8-inches (20 cm) below your waist measurement.
You can also include a softer fabric i.e. non-starched, in your corset for additional comfort and a softer inner lining. Utilize scrap cotton to make a mock up from and slice the fabric following the pattern design for the corset as it is, then make alterations if needed.
Test a thread first to check the quality of the bond when you pick thread for your corset. It needs to take a great deal of strain within the corset if it does not separate easily and you want your corset to be durable. After you are satisfied with the thread and the corset fabric you have chosen to use for your corset, you can now start corset sewing according to the pattern chosen. Sewing should be much easier and quicker if the corset pattern is already pre-cut.
