Putting on my "historical guy" hat, I'll say that the uniform in the OP follows the style of a fairly standard Scottish military piper's Number One Dress uniform.
Here's the "real world" equivalent, being worn by the pipers of the 1st Battalion The Royal Regiment of Scotland.

I think the OP's plaid (pronounced "played") is OK, it's just not put on right.
Civilian pipe bands wearing military-style No1 Dress always face two challenges:
1) acquiring all the parts of the uniform
2) putting everything on correctly.
It's very common to see these civilian No1 Dress bands have all the right things but be a bit sloppy in how they're put on.
The plaid is the trickiest part. There are several "correct" ways to do it, it varied by regiment in the army.
There are YouTube tutorials, for example one by ex-Scots Guards piper Peter Harvie showing the Scots Guards method:

My first pipe band had an ex-Cameron Highlanders piper who taught us a quite different way.
Anyhow the only things in the OP's uniform that deviate from a proper piper's No1 Dress are the hose, and the lack of the crossbelt.
No1 Dress always calls for diced or tartan hosetops with white spats.
A couple notes:
-the OP's uniform is clearly based on piper's dress. In the Scottish regiments the "military band" (brass band) didn't dress like the pipers.
-the OP's doublet has the buttons in groups of threes, which in the British army is only worn by the Scots Guards (Third Guards).
