I always send a little style guide when you book, but the short version is: stick to soft, neutral tones (creams, whites, dusty blues, sage greens, warm taupes) and avoid busy patterns or logos. You don't need to match perfectly — just coordinate loosely so you look like you belong together. Most importantly, wear something you feel comfortable and like yourself in. If you're tugging at your clothes all session, it shows. Comfort first, always.
