I don't dance any more, but during some 25 years dancing in most sides I knew the dancers made their own kit. Straightforward stitching of leather, or ribbons is well within the capacity of most folks, and you are probably selling yourself short unless you have an actual physical problem with needlework.

If you have seen the kit on your fellow dancers you must have a fair idea what you are aiming at, so I would suggest that a good starting point would be to assemble the bits you have been given and try laying them out as a mock-up. Check whether you will need any more bits (for instance several sides using leather dog collars to hold up bell-pads expect you to supply these yourself). Try pinning the bits together and trying for fit.

All OK so far? Some fabric or leather sewn parts can initially be assembled using glue (copydex or similar) so that you can possibly make the whole thing as a try-out without sewing, though not all kits will be amenable to this approach. Do not, however, expect it to last. If the glued version fits & looks OK you will then need to sew it (no need to disassemble, just stitch through the glue) in order to achieve something that will withstand the rigours of dancing.

You have been practicing for 6 months so you must by now know at least one or two other dancers well enough to get a bit of assistance if you are really stuck. Even just borrowing someone else's kit for a few days will enable you to take a close look at how it is put together, you may well be encouraged by just how crude the assembly can be, yet still function perfectly well.

Give it a go, you have little to lose except your dignity.
