At the trial we talk about your dress, the kind of celebration you are planning, and what you are genuinely comfortable in — pinned or loose, classic or a little undone.
Depending on your hair type there is professional advice worth hearing so the style holds through the whole day. The weather has to be respected too, and that conversation belongs here rather than on the morning itself.
The same applies to makeup: coverage that softens what you would rather not see without masking your features, a lipstick that survives being kissed, and mascara that lets you cry. Above all, be yourself.
