Choosing clothing colours for your photos is essential. If you've come to me, I believe you like my style, and to be able to match it, it's really important that your clothes are following my palette. White, black, brown, beige, moss green and all earth tones are my favourites.
They're absolutly the best option for photos, since patterns create busy images, leading to visual overload, diverting the focus from what really matters: you.
Plain fabrics are also timeless so you probably won't get bored of them that easily.
So remember: less is more. The cleaner the better.
