I hate to contradict, but on my best kilt. a traditional from Connell Reid, there are in fact two sets of loops.

The very wide ones to take a belt, and inside them-small ones for the sporran strap.

Now for day to day use they are not necessary: however if wanting to keep everything in place, more so if wearing say a dirk etc, then they are required.

The same applies if on a hot day one is in shirt sleeves, for a kilt and belt that are out of alignment can only look sloppy. It is the same in respect of the sporran strap.

To try and clarify the above, think about wearing a Sam Browne and sword, or a side arm for parade wear: and how sloppy such things can look if the belt is too loose, all over the place, or out of alignement with the tunic and trousers.

So as mentioned above, most of the time such things are really not very necessary: but every now and then there is an occasion when they are vital if one is to maintain a smart appearance.

So though most of the time I do not bother with the loops, I certainly expect them to be provided: both on my traditional kilts, and the hillwalkers I wear on a day to day basis.
