Now that I have a well fitted basic bra. I can use that pattern to create a sloper. Bare Essentials shows you how to create a sloper and how to use that sloper to create any design bra.
If you are creating a sloper using Adobe Illustration, creating the style lines on different layers will allow you to turn the layers on and off so you are not overwhelmed.
I used the sloper to create a diagonal bra pattern.
