Hair is without doubt the most important changeable feature we have. The way you wear your hair can make you look taller or shorter. A hair style can emphasize your features or de-emphasize them. When choosing the hairstyle for your wedding, it is necessary to consider the following:

Facial features or Face shape: The shape of your face is a key factor in deciding what type of hairstyle to go for.

Heart-shaped face must choose:

Sleek sweep parting and gentle curls.
Avoid a long, sleek and straight styles.
Square face:

Choosing curls and waves helps soften the face.
Also avoid long, sleek and straight styles.
Oval face:

Any hair style will look good on an oval shaped face especially any style that adds width and volume.
Avoid anything that hides your face especially heavy fringes.
Round face:

Choose long sleek straight styles or any hairs style with your hair taken away from your face. Round faces are also perfect for your high up-dos' to create more length.
Avoid volume, curls or anything that adds width to your face.
Another thing your should consider is the wedding dress.

If your wedding dress is a high neck style, it will be appropriate to wear your hair up to show the beauty of the dress.
If your dress is emphasized, then it will be necessary to do a simple hairstyle so that it does not take attention away from your dress.
If you are wearing a boob dress or a spaghetti straps, then you can consider wearing your hair down or some of it up and down.
Consider also the theme of the wedding and choose your hairstyle accordingly. For example if you are doing a informal wedding, you could wear your hair down in loose curls.

Also consider the ambiance of the wedding. If it is a garden wedding, you could do nice braids or loose curls.

Taken all these tips into consideration, you could have a sweet perfect look on your wedding day.
