One item may be of the very finest quality (bespoke to your specifications) - The Kilt of course
One item will be of very good quality - The Sporran and Belt because I hate the stiff inexpensive ones.
One item will be of good quality - Socks for comfort
One item will be of average quality - Sgian Dubh
One item will be of low quality - Kilt pin

I would skip the jacket and put the money into the kilt and sporran.
