How do I look good?

Medical-warehouse-drivers...Like as in DME? And no suit and tie? If something like that, I'm thinking well fitting khaki pants and sport jackets, with open collar shirts

Where I live, places like Mens Wearhouse - where they sell/rent tuxedos - they also sell men business attire, and do custom tailoring, etc. Do you have anything like that, where you live?

No matter what you wear, be sure it FITS

Yeppers, the world of DME.

Where I work (insurance company) we just went to business casual within the last year. A lot of the men wear khaki slacks and button down shirts. Make sure to get them no-iron to make it easy to look crisp (and as the others said make sure they fit well): Lands End and LL Bean are good sources.

My son is a professional and he said never wear short sleeves if you want to impress. Just my 2 cents

That's what the sport coat I suggested was for...to cover up the arms...

But what the hell do I know about dressing a man?

I'm just a woman :)

Unless you live in Texas! It's too hot to wear long sleeves here in the summer.

My four tips for men looking to step up their style:

• Do not wear short sleeved button-down shirts. Buy long sleeve collared shirts and roll up the sleeves. http://www.esquire.com/style/mens-fashion/advice/a29402/how-to-roll-sleeves-2014/
• Match your socks to your footwear. Sports socks with sneakers only; dress socks with other shoes; NO SOCKS with open shoes!
• Select clothes that are fitted. Nothing worse than wide, flappy shirts with the shoulder seams hanging down your arms.
• Wash your jeans. You may think you can get away with wearing them a few times, but trust me, the baggy arse and knees will always give it away.

Not judging men who don't follow these (my husband lives in short sleeved button-downs). As a magazine publisher I've written and edited a few pieces with these tips.
