ive heard of this before about wearing a kilt pin for weight. I recenlty bought a PV kilt (an 8 yard kilt which is supposidly 16oz which i doubnt it is that heavy)

ive had no problems in the gusty winds of glasgow, ive had the pleats messed up from gust of winds but its never left me bare.

When i was ;last at a wedding i hired a kilt, which was obvioiusly a real wool kilt 8 yard and quite heavy. the kilt pin really did not feel like it had any weight to make any kind of different.

i have virtually no knowledge of kilts and accessories, but it really doesnt make sense that the kilt pin functions as a weight. this is just my own personal observations.

Even with my light weight PV kilt i wouldnt feel a pin would offer any advantage to keeping the apron in place during wind. Unless it was made of lead.
