Easy Unlined Jacket? That,s telling porkies

If one is told that making an unlined jacket is easy,Abi says that,s porkies ( cockney slang for lies.Porkie pies ?get it)
I line most of my garments, even line/cotton summer togs.I had just finished a duo , skirt and jacket combo in a silk/linen/tencel fabric.
Yummy colour , feel and drape but not suited for anything structured.
Unlined jacket.Yikes , with the overlocked seam edges exposed.
No I dont think so. Not very pretty

The alternative was to draft a half back lining , front part lining by extending the front facing to match at side seam similar to armhole chest piece or plastron.
Description and details for drafting the lining pieces can be found in Singer Tailoring or Taunton Press Easy guide to lining( I dont advocate blatant copyright violations)
Fusible knit interfacing cut to match the lining pieces, shaving away 2 cmm at outer edges, with pinking shears to soften /reduce strike through.

HongKong finish on every exposed seam edge tadded a few hours to project.Lucky I had Ambiance lining bias roll( from Paul Costeloe factory sale)
Perhaps twice or thrice as long as it would have taken to sew a full lining.

MORALE EASY IS NOT ALWAYS FASTER
