Sorry, I didn't explain clearly enough. Most of the office wears the polos, but most of "my level" and ALL of those above wear suits of some degree (some wear blazer with slacks, a couple wear full 3-piece suits, etc.) So a suit won't be out of place for me, at all. And I will definitely need one the days I am meeting with Corporate officers... they're all wearing them - unless it's a golf meeting.
That's a great idea, I didn't even think of blazers. I might look into that more.
Part of the reasoning for the suggestion that I upgrade my wardrobe is that I am expecting another promotion by year's end, as well, once I complete my licensing. Once licensed, it's been pretty much put in writing that I will become a manager, as our office has over 100 employees, but currently only 4 licensed architects (I will be #5...) So this upgrade is just the first step in what I foresee to be many more upgrades. On a plus side, the Manager's promotion will come with a decent pay increase!
This said, don't *****-foot around with cheap "this'll do for now" suits.
we're talking about your career here, so go big or go home. But one great suit that you will be glad you have five years from now (after the promotions &c.) When the budget allows, buy a second.
