Ladies, wear something you can move around in! Long flowy maxi dresses are one of my favorites to shoot, just by the way they move. It will add some unique visual elements to the photo!
It is good to consider your background + select colors that stand out from your background.
Examples:
Beach - Avoid tan
Forest - Avoid green
Limit patterns to one or select few depending on group size. For larger groups, if more than one person wears a pattern, keep it simple. Patterns can add depth to the photos, but less is more!
IT IS BEST TO AVOID BRIGHT COLORS.
IF YOU ARE planning on STEPPING OUT OF THE NEUTRAL FAMILY OF COLORS, ITS BEST TO avoid patterns.
NEUTRAL COLORS ARE ALWAYS THE SAFEST BET!
