It's all a matter of means and priorities. No right or wrong.
Having said that, I tend to feel guilt whenever I buy myself something that I maybe do not really need. Maybe that money would be better spent elsewhere either now or later?
My parents (who lived through the great depression) were not not status or luxury seekers yet lived a very comfortable yet not very showy middle class existence. That in my background is a big influence on how I think about these things. Plus perhaps the fact that I grew up in an area with a large Amish influence though my family itself was not Amish has an impact in how I think and my values.
It's all good I guess as long as you are able to keep a positive healthy and open perspective and some reasonable balance regarding priorities in your life and not become excessive/compulsive out of fear or some other negative emotions like envy, etc..
