What Does Formal Dress Mean?

[JoObrien7]

I have been invited to a Charity Dinner with my husband and the invitation says lounge suits for men and formal dress for women. I googled it and all these long dresses appeared ... I don't like long dresses they make me look fat.

Can anyone help?

I am thinking of wearing black ... what does everyone think?

A dressy frock, or a cocktail dress, a
black dress will do it too.

I have blonde hair so black does suit me.

By saying formal dress they aren't limiting you to wearing a dress per se. You could wear a tuxedo pants suit or a dressy jumpsuit. Ball gowns with lounge suits would look odd.

I am going for a black dress .. I don't want to stand out.

I'd go with cocktail length.

They have specified lounge suits because, if they didn't, some people would turn up in their best jeans.

Assume it's an upmarket event and dress to impress.

Black will also be perfect!
