How many suits do I need?
How many suits do I need? I'm changing from active duty military tothe civilian sector at 38 years old. I will be working from homebut travel will also be involved. I have an upcoming conferencethat will require suits for 6 straight days. How many suits do Ineed to realistically buy?
I would buy 3 jackets and 2 pairs of pants that match all, theywill assume you are cleaning jackets just allow time betweenwearing and rotate and even if you don't clean they will probablyot know if you are careful and if you must hotel probably has acleaning service
