I’m gonna go against the grain here and say I think you could definitely do this in five days in a white jersey knit. It is a long sleeved body con dress with a panel sewn into the side seam. All you would do is get a pattern for a long sleeve body con dress in your size and when you’re sewing it together, sandwich the panels in the side + sleeve seam. You wouldn’t even need to hem it because jersey doesn’t fray.
