According to diy-wedding-planner, as a general rule of thumb when choosing a wedding hairstyle an “All-Up” hairstyle is very sturdy and will last all day and night whatever your venue. It is suitable for morning, afternoon or evening weddings.
“Half-Up/Down”hairstyle is still sturdy and should last for the duration of the wedding and wedding reception dependent upon the type of hair. It is a romantic, quite young look. However, it does not go well with evening wear,
“All Down” hairstyle is not practicable for outdoors, unless your hair is particularly short or you can guarantee that there will be no wind! Whilst it is romantic and modern the style may not last as long. You should be prepared to touch your hair up inbetween events.

Here’s what I think, go with the look that suits your features best. So that’s what I’m going to focus on during the hair trial. However, I’m not really into tight neat updo’s, (unless in I’m need of a relaxer 🙂 but I haven’t excluded them.
