There are a number of elements that should be integrated into the envelope design of a pattern for men’s clothing:
A perched leg
Make use if what is available- such as an empty barrel…
An item to hold
Cigarettes give a great Don Draper feel, especially when one is indulging in one’s underwear.
Or hiding one behind one’s back.
Items that can be associated with sleepwear: an alarm clock being looked at with uncertainty, a journal, or yawning.
The outline of a flask really says one is about to do some serious negotiating.
Encourage an active lifestyle with weights being lifted up to one’s mouth.
And again, make use of what you may have available, such as a lasso.
A place to put one’s elbow
Integrate weekend-at-home elements, such as the top of a fence.
One’s own knee.
If home elements are not available, air works just as well as an elbow perch as a knee perch.
Finally, elements may be tastefully combined to create a striking image.
