For anyone (or me) that plans to attempt this again in the future, here are a few helpful hints:
Sew collar together first
Turn it right sides out before you attempt to sew armholes to armhole lining
Wrap lining around through the color to attach right sides together at armhole and sew so it looks like a long tube.
Then, you will be able to sew the side seams (lining to lining, fabric to fabric) down
(Kind of like doing pant-leg holes)
Lastly do the bottom hem.
If you do it in any other order, you will be stuck with a garment that will not turn right sides out and end up spending more time watching sewing you-tube videos and unpicking your work than you would like to admit.
