I used to wear cotton long pants (thermals) all year, under the suit pant. Not letting the suit pant touch the skin made it easier to wear it for a very long time (multiple months) before dry-cleaning.
It was 98% humidity and 70 degrees at 7:30 this morning. I broke into sweat watering plants with athletic clothes on. It’s now 86 degrees and 65% humidity. Spring has only started.
For me it’s not an option. I have to dry clean. It is easier to find alternative materials to cotton for the office but they don’t replace button downs and jeans. They can’t replace a suit, linen is still much too casual.
Don't miss those days of mandatory suit-wear.
