David has a wardrobe standard

Personally, I wear a bunch of navy colored Polo Shirts and it seems to be the standard in the industry with engineers from various companies.
The navy color means they don't show the stains, they look smart and most importantly for me, they don't need ironing. Wash them and immediately hang them up to dry indoors, perfect.

Love the podcast as always.
