Let me give you the same advice I give all my customers.

First. Ask yourself what do you want to do in your kilt.
This will help you decide what features should be on your kilt.

Then ask yourself how you want to look in your kilt.
This will help you decide what style kilt you should choose.

Then combine the answers to these first two questions to you own personal style.
This will help you decide which kilt maker you should choose.

Each of us offer different features.
Each of us offer different styles.
And each of us offer different looks.

If your personal style tends towards that seen on the Utilikilts website then your choice is pretty clear.
For an alternative or Steam Punk look then an Alt.Kilt is your choice.
If you prefer a bit more traditional look then perhaps a Freedom Kilt would be your choice.

Try to look beyond the fabric as we all use much the same in fabrics.
We all have pockets but what style pockets will suit what you want to put in them.
Then finally try to look beyond the bits and bobs added to the kilt and look closely at the pleats, the aprons, and where the kilt is worn.

I think if you concentrate on chosing your kilt based on these things you may be able to narrow down your choices a bit.

Then, finally, call or email each of these makers and talk to the person who will make your kilt. Are they willing to work with you? Are they willing to listen to what you have to say and willing to take the time to talk to you about your choice? And then, most importantly, will they be open and up front with you about the product they offer.

Kilts are a very personal garment. This one piece of clothing, more than any other, must be compatable with your personal lifestyle and your personal style. Even if you choose an off-the-rack kilt sold by waist size it will soon adapt to your personal style. (Or you will adapt to it.)

So talk to your kiltmaker. Talk to other kiltwearers. Post here with lots of questions.
Take your time. Become informed and knowledgable. Only then will you still be happy with your choice three, four or ten years from now.

It is your hard earned cash. You should get exactly what you want. Don't settle for less.
