Search for highland wear and you’ll most likely get confused when you see all the things that canor “should” be worn with a kilt.

Fortunately we are talking kilt as casual or informal wear.

Therefore we can make the accessorizing pretty simple as well.

Leather sporran for daily wear and without tassels. From £20, average may be around £50.
 

A so called  Rob Roy Sporran is perfect for casual wear. About £50. This one combines the colours black and brown.
 

Belt & Buckle. Looks good with a kilt. 6-7 cm wide. From £20.
 

Kilt hose or kilt socks. Buy from them from Brevin&Co.
 

Garter flashes for keeping your socks stay up. Or make you some invisible ones by means of Velcro straps.
 

Kilt Pin. Won't be allowed worn on aero planes.

For casual wear I think flashes are over dressing. Therefore I use garters made of Velcro strips

Where do I put my stuff?

For a traditional kilt you need “pockets”.

Most kilt wearers will use the special purse, called a sporran, which is to hang on your front.   

What sporran?

Go for a plain leather day sporran – without the noisy and annoying tassels most sporrans on the market come with.

There are two types of sporrans, which you may just as well forget about:

Semi-dress sporrans often come with with a front of seal skin. They are illegal in some countries.

Dress sporrans are for formal functions only and therefore out of the question for casual wear.

I will almost almost wear a day sporran.

Is a sporran a must?

The same kilt (Caledonia Tartan) w and w/o sporran.

No. For casual wear you might instead simply use a belt pack. Or you have the pockets you need in your jacket or photo bag or whatever.

Do as you like. I think a kilt looks better with a sporran and to most people kilt and sporran are strongly connected items.
   However going without one adds to comfort and therefore I, too, sometimes leave it at home.
   With modern kilts having pockets I will never wear a sporran.

For a day sporran you'll have to pay about £50. You might get them cheaper as well as far more expensive.

Sporrans are with a very few exceptions delivered with a metal sporran strap. For casual war I prefer a leather strap. It is a simple DIY project.

What about a belt?

A belt is purely decorative. The straps and buckles of the kilt keep it up securely. But to my opinion a kilt looks at its best together with a 2 ¼-2 ½ inch wide belt.
   An original kilt belt & buckle might in fact be a little bit overdressed for casual wear; nevertheless it matches the kilt and wide-enough ordinary belts are hard to find. Men’s ordinary belts (4-5 cm) look wrong with a kilt.

Prices from £20.

Men's ordinary belts are not wide enough. Won't work.

On your feet?

Long socks, called kilt hose are common with the kilt. To keep them stay up you might also need garter flashes.

Finding flashes overdressed for casual wear? Use some cheap Velcro strips instead - invisible when your socks are folded down just below your knees as they should.
   For casual wear you might also scrunch or roll your socks down.

White socks are not to everybody’s taste; nevertheless most kilt socks are probably white or off white.
   The reason might be that they'll go with practically every kilt. Other popular colours are black, lovat green, lovat blue, bottle green, dark grey and navy. I have socks in most colours, including white ones.

In the summertime you might also replace the kilt hose by ordinary short socks.    For casual wear the better solution, in my opinion, but traditionalists shall object to this.

Even when it is cold kilt hose is sufficient to keep you warm and comfortable. Never ever think of wearing kind of panty hose.

The kilt pin?

A kilt pin is for pure decoration, too.
   If you buy one, remember it is NOT intended to keep the layers of your kilt together. That should ruin your kilt in a short time!

If you want one, it is cheap, about £12.

The safety pin is for mini kilts.

And the other stuff?

Forget about it.

All other accessories are unnecessary for casual kilt wearing.
   Wearing of the special knife, the sgian dubh in your right (or left) kilt hose could in some countries bring you into jail and even more so the dirk. (You can buy harmless sgian dubhs made of plastic).

The bonnet, feathers and cap badges are too much national dress and should look, worn by a non-Scot, rather ridiculous. And so do the special shoes, Ghillie Brogues, kilt shirts (Ghillie shirts) and playds over the shoulder.

What else to wear with the kilt?  

The kilt not being national dress to you, keep it simple:

For the upper part of your body wear what you should else be wearing, whether a regular shirt, a polo or a t-shirt.

If you need a jacket you’ll have to buy a special kilt jacket, however, probably an Argyle or a Braemer. A Prince Charlie is only for very formal occasions (black and white tie functions).
You might also have a seamstress to alter one of your jackets: Much shorter and with a rounded front, in order that the jacket does not hide the sporran. 

Forget about men’s ordinary jackets. They are too long and look ridiculous with a kilt.

If it is merely a question of protecting yourself against coldness a short wind breaker or anorak will do the job efficiently and look nice with your kilt.

On your feet wear shoes fitting the purpose. For casual functions and especially when wearing modern kilts many men prefer heavy-duty shoes or walking boots.

Never wear long boots reaching to your knees or some kind of tights. 

Where to buy the accessories?

For your first kilt you may buy it from the kilt vendor.  Many of them have price offs on kilt packages.

BUT sometimes these packages comprise items that you DON'T need. So what in the first place looks like a bargain can be an expensiver solution.

"Necessary" to me is only sporran, belt & buckle und kilt hose.

Kilt hose you should by all means order by Brevin&Co. Prices are favourable and quality high.
