But honestly — the most important thing is this:

Wear something you feel good in.

If you’re comfortable, it will always photograph well. I want this to feel like you, not a styled version of you.

Soft, neutral tones and simple textures always work beautifully, but there are no rules here.

If in doubt, keep it simple and let the location, light, and movement do the rest.

Here are some examples of my couples for ideas of what to wear and what setting/ venues you might like.
