Hello Sir, please I have a task I need to get done, it is about opening up the chest of a jacket model don’t know how I can get this task done please did you have any idea you can share me?

Welcome :tada:

… so not only the jacket is closed but also the model has no border at the opening but is closed ?? Like an O instead of a C ?? I think you have to elaborate this…
