I tried to use the search function but had no luck. Sorry

Quick question. I have read that if you want to get a fly plaid you should get it from the same run as your kilt cloth if you want it to match. Does this apply to the colors as well?

What I am trying to figure out is if I want to have a vest and a hat made to match a kilt. ie a red vest and hat (for Christmas) to match the red in a kilt (ie Robertson) Do you have to get it from the same manufacturer and in the same weight? or are the solids fairly consistent?

I am fairly new to the communty and am still learning.

Thank you

Ray
