Nice Sheriffmuir doublet! The facings are unusual but give it individuality. Overall a very fine outfit.

However, I would loose the tie and use the belt for day wear without a waistcoat.

Matt's good advice to wear a cravat is worth taking. I favour a white cravat with the Sheriffmuir. This can be worn tucked into the waistcoat or outside the waistcoat, especially if trimmed with lace.
