I wonder if I can put darts in my new top

I bought a new top, its a comfortable fit but it’s a little “blousy” on the body, the arm and shoulder movement is good, so I’m wondering about darts.

It’s a copy of the long range desert patrol smock, its very cool (temperature) to wear and if it was made of the original Ventile cloth (tightly woven wind proof cotton) it would have been very expensive.

I like it because it has four cargo pockets on the front and schlepping the DDs’ from place to place, jeans pockets just don’t cut it.

A size smaller and it would be too tight on arm movement, so I’m hoping a trip to one of the seamstresses in the borough will sort it.
