It is not too wrong to say that a wedding ceremony is like a play. The main hero and heroine are, obviously, the bride and the groom. The elements of the play are numerous – the secondary actors (the guests), the scripts (the events), the main participants, the decorations, etc.. You can’t just decide on one element without taking into consideration the others, so a more holistic approach is necessary. When picking mother of the groom dresses, this should also be kept in one’s mind.
A mother of the groom’s role is to be a support for the groom and the bride, obviously. She is not there to dictate the rules for the wedding, so a consultation with the main characters is necessary. The bride and the groom will tell her, what colors they would want to see on their weddings, how much formality is expected, and all the other things. When picking mother of the groom dresses, it is important to fit into the theme and the design of the wedding that the main couple decides on.
We also recommend that you take a look at what mother of the bride wears. Maybe take a look at bridesmaids’ dresses, too. Your goal is not to copy their dresses, but to pick something that complements their designs, both in colors and formality. For example, putting on a pantsuit when everyone wears gorgeous evening dresses will not look harmonious. Generally speaking, a MOB dress should be a bit dressier than a MOG dress, and the bridesmaids’ dresses, while on the same level of formality, should be a bit blander than the MOG dress.
If you have any other questions regarding this topic, or maybe you have questions regarding other wedding topics, like where to find a good Chicago wedding photographer or something, you should try Q&A websites, like Yahoo Answers, or better, wedding forums – theknot, for example. Google is fine, but getting answers from real people is better.
