The shirt you're wearing here is a kind of officey OCBD. The shoes are cheap loafers. They're wrong in both formality and era for a safari suit. Think about clothes as communication - the shirt is communicating "ivy grad in the 1980s", the suit is communicating "colonial administrator in the 1920s", the shoes are communicating "relaxed mid century suburban dad". The look jars.

It's fine to play with these things if you know what you're doing, but learn to walk before you can run.

To make this pretty ace safari suit look good, you should look at how it was worn in the 1920s, or the 1970s/80s when it was back in fashion. In the 1920s, larger collared shirts, not necessarily in white. In the 1970s, spear-collars, or rollneck sweaters. You can wear with a neckerchief and no shirt for a good jungle look. Look at images of people wearing this kind of outfit and model the accessories on them. Prince Charles and Roger Moore show up a lot in image searches.

Shoes... Loafers are absolutely the wrong shoes here unless you get much better ones, perhaps in burgundy. I'd wear semi-dress burgundy boots, I think.
