As an amateur but competent sewist, i wouldn't want to go near that😬
It has lines down the front which means that it has been sewn there using darts and will probably be lined.
That means that i'd expect to have to
- seperate the inside lining and outside
- decide whether to replicate the darts by sewing a few pieces together to continue the line or just create a single panel. If replicating darts, will need to line them up precisely.
- The description says it has buttons at the back so will need to match them and add buttonholes.
- You'd need to turn it back the right way, press, and hand sew the lining and outside together again.
Added complications is it says its lyocell which can add stretch but it looks quite structured so you'll need to find the right machine settings.
Sorry! It can be done though. And if you do, I'd love to see how you get on!
An alternative could be to add a peplum m, lace or a ruffle which would be much, much easier.
