It might actually be cheaper to buy light leather for chaps, than to do Ultrasuede. Last I knew it was over $25 the yard. Leather does hang well, with the added weight.
Try looking at a Quarter Horse Journal, they are the style leaders in all things Western. Hobby Horse is where a lot of folks get shirts made, so you can see what is being presented for next spring. They have a site if you do a search. Some zipper jackets are looking very good, not sure if the swirly braids and overlay patterns are still so big. Bling is still around, but you need to see what is current or old. Sometimes less is better.
We have done lower level Western, 4-H shows, where things are not so elaborately done. I made my daughter’s shirts, though you have to hunt for fabrics. Kids were wearing lycra stuff, bright colors in her kind of shows. She has been out a year, so I am not current!
There is a new shape for hats in Halter and Pleasure, oddly flat front brim, with sharp upward edges on the sides. Maybe you could just have an older hat recreased in the new style, if you have a good Tack store nearby. Do check out boots as well. I didn’t let daughter wear any of the low heel, crepe sole boots to ride. Halter and Showmanship was OK, but not in stirrups. Unsafe with low heels, sticky soles, though ALL the big name folks, winner’s photos showed those boots the last time I checked.
We have local ladies who sew shirts, they come to tack sales and advertise in the local horse papers. Often they sell the fancy fabrics, jeweled trims you can’t locate other places. Even had jeweled zippers! So that might help you find what you want for “the LOOK”.
A suggestion is to have a Serger machine for seams. That is an IMMENSE help to making the clothes look professional. The new fabrics can be VERY difficult otherwise. Western clothes are NOTHING compared to trying to make swim suits!!
