Not to be confused with baggy, wearing something comfortable you can move around in is essential. You don’t want your clothes to restrict any movement or position for your session. Also, staying away from heels is excellent idea unless your session is formal attire
Avoid wearing the same color as it makes for a dull photo. Instead, choose 3-4 complementary colors and coordinate through them. For family photos, couples should wear different colors to avoid clashing. Breaking up the color is key for a dynamic and interesting gallery.
Stay away from the neon and over-saturated colors. Instead, go for something airy, muted, earthy or soft. This will make you the center of attention and make your photos timeless.
Stay away from big patterns as they can be distracting and unflattering. Stick to solid colors or smaller patterns for an interesting wardrobe. Avoid clothes with text or logos as they draw attention away from the subject. Keep it simple, solid, and timeless.
