My Jacket

My jacket's either black or blue -
Does this stuff happen to you, too?
I bought it thinking it was black;
If blue, I wouldn't take it back.

Yet now my scarf and gloves don't match 
If it is navy; that's the catch.
If it is black, then I'm okay;
Its looks change every single day.

To solve this puzzle, I'll be wise 
And splurge when I accessorize 
On choices that will be evolved
To match them both - my problem solved!
