Start with the venue and the season, not the trend cycle. A satin ballgown sings in a candlelit hall; a light appliqué gown moves beautifully in a garden. When the setting leads, the silhouette follows.
Book fittings eight to ten months out, and bring only two trusted opinions. Too many voices blur your own. Pay attention to how a gown feels when you sit, hug, and dance — you will do all three for hours.
Finally, photograph each contender in natural light. The mirror flatters; the camera tells the truth about proportion, texture, and how the fabric reads from ten feet away.
