Blouse:

Same cut as British Pattern 40, so this was likely produced immediately after WW2 (if authentic).

Stamps:

“Haeren” means that the country of origin is either Denmark or Norway. 

Pockets:

Epaulettes:

Zigzag reinforcement stitching on back of collar.

Buckle:

Buckle is much simpler than British version.

Cuffs:

Inside:

Pants:

These pants were probably tailored to resemble WW2 Pattern 37 or 40 Battledress trousers for theatrical purposes. It is unclear if these belong with the blouse above.

Stamps:

Crown appears to be Danish (matches crown on Danish P37 webbing).

Cosmetic Thigh Pocket:

This “bandage pocket” on the left thigh (as worn) is purely a cosmetic patch and is completely non-functional since it is stitched closed at the top, meaning it cannot be opened.

Cargo Pocket:

Fly:

Button fly.

Inside:

Ankles:
