For anyone looking for a Lavinia Mitchell saddle, I have a practically new one that I'm selling, 17.5", really wide!! Comes with the shim sheepskin numnah and shaped girth
My 5yr old RID has a Heather Moffett Fhoenix soft tree dressage saddle. It's easy to adapt the fit with the panels and shims so I haven't had to swap and change saddles as she's been growing. I went through 6 treed saddles with her dam from the ages of 3 - 5, losing plenty of dosh in the process!
