It depends on the Tartan, I have Seen a Leather Neck Tartan that was Pleated to the Stripe and it had yellow Stripes Verticly, but i also say a tartan that was pleated to the stripe and it was awful
looked like 2 large green stripes going horizontaly
i think it just depends on the tartan and what stripe on the tartan it is pleated to.

this is pleated to the set
where as this is to the stripe

not the best, but all i can find but if the tartan led itself to it regimental pleating would look great but i think that having a bright contrasting stripe to pleat to makes the diffrence. [/img]
