Deciding what to wear to any Wedding can be a tricky task, but when you're the Mother of the Groom, it is very important to get 'the look' right!
Firstly, you don't want to upstage the Bride. You might have known the Groom for a lot longer than the Bride has but its their big day - not yours or the Mother of the Brides.
Secondly, think colours. We all have colours that suit our hair and skin colour, but I would suggest that you avoid cream, white, Ivory - all those traditional Bridal colours.
