If you are wanting to keep in line with a simple/minimalistic look, then I suggest neutral colors and textures. I’d think along the lines of colors that are more muted than bright. You can choose textures with a small pattern, but are not too flashy. Keep in mind that you and the emotion you portray are the main stars of your shoot, not the colors and patterns on your clothes.
Consider dressing monochromatically to elevate your look while keeping simple colors as your main palette. Read more here.
If you are wanting a shoot that is light, bright, happy, and energetic and you want to stand out from the backdrop, then choose textures and patterns that portray a brighter look. When it comes to bright colors, I do tend to edit with more muted tones. So any bright colors tend to be toned down a little when your photos are edited.
Keep in mind that bright neon colors (oranges, yellows, bright reds) and strong patterns (like smaller stripes that are close together) can reflect back onto your skin and cause odd discoloration.
