Summer: Wide strapped tank or t-shirt (sometimes if it gets hot riding I will roll the t-shirt sleeves), dark brown light fabric breeches, paddock boots, & half chaps.
Winter: Same as above but thicker socks, my winter riding gloves, sometimes a thin “puffy” vest with a warm jacket over it… sometimes just the jacket. On super cold days I will also layer a regular t-shirt over a long sleeve t-shirt.
For lessons I put my hair in a bun on top of my head with no hair net. At shows I wear a hair net. Of course in both situations I wear my helmet.
