I have trouble finding clothes that look good on me. I'm 5'10" - 160 pounds and 52 years old. Anyone know where to find casual clothes that look nice?

Hi,
Roaman's is a good place, online, or through their catalogs.

My wife orders things from them, and gets compliments when out in public and from her friends. QVC also sometimes has good looking clothes, which she orders occasionally.
Best wishes.

Without measurements I will assume average size proportions for weight.

But that is about average size and off the rack should be easy to find.

But I will say that if you want better fits go to higher end stores depending on your budget.

Also options, a scarf to wrap around the waist, a vest along with a blouse.

Make sure your undergarments are the best you can get, often without proper fitting, they will destroy any look.

And of course styles have changed over the last 20 years, I don't know if you are trying to dress like a 20 year old or wear what I call "old lady" clothes. Sometimes it is merely style changes that we don't like, so we don't see ourself in them looking right on us.
