Update:Started doing some work today. Couldn't go to the fabric store because my dad had to work some overtime.
So first, I already picked out my bodice pattern as you know.
When you buy a pattern online it comes in a big puzzle that you have to cut out and put together:

After I cut it out and assemble it the pieces look like this:

I had some left over fabric from Scarlet Sprite, so I figured to make a trial version

Here is the result:



The overall fit is good, and the pattern takes very little fabric (Hooray!)
I need to modify the pattern to accommodate wider straps and use a less slippery lining, but I am extremely happy with the result so far. Can't wait to do this in the real fabric~!
Also this top is super comfy and lightweight. Love love love it!
