These photos were taken at HITS, 2018. The first two photos feature small shops that deal mainly in saddles and bridles, etc. I noticed two things about them: 1) many of the finest saddles are made in France and 2) they are very expensive. As I recall, the saddles start in the $4,000 range and go up from there.
The last photo features a tack shop, which sells a wide range of equipment used by horses and riders; not just saddles but also clothing, boots, etc.
