Mother of the Bride/Groom Style?
Mother of the bride/groom style will depend on the theme of your wedding.
If it is a relaxed beach wedding, then a summer dress and light cardigan will work nicely, if it is a more formal affair then possible a dress and jacket, or skirt, blouse and jacket.
The outfit can be custom made, or purchased from the rack. It may be a good idea to ask at the dress shop where the bridesmaids dresses are being ordered whether they make that type of outfit to order. This then means your dress will be arranged along with the bridesmaids dresses in time for the day and fitting you perfectly.
You can then be involved in the dress fittings and lead-up excitement with the bride and bridesmaids. If you have a dressmaker in mind, she may have some common outfit designs to choose from, or you can pick a pattern for her to follow. You will also need to arrange the fabric too.
When picking a style don't automatically pick an outfit to hide the body parts you don't like so much.
Ask a store fashion consultant for some advice on outfits that enhance your assets, not your self-conscious areas.
And also, remember to shop with any under garments you will be wearing on the day. Brands like Nancy Gantz help to ensure your beautiful outfit falls as it should all day (see shapewear )
