Flattering riding gear

[purplepencilcase]

Sadly I'm size 16 and look fat on a horse these days!
In the hope of not looking like a complete muppet, what riding clothes are most flattering? I'm desperate for ideas!

How often do you ride and what kind of riding do you do? Unless you’re competing regularly, you don’t need to kit yourself out in Ariat/Pikeur etc from head to toe. Thicker riding leggings/breeches in darker colours do a better job of holding you in and you don’t need to wear skin tight tops - normal t-shirts/sweatshirts are fine and don’t show every bulge
