What to Wear for Wedding or Formal Dinners?

Sometimes, I run out of clothes to wear for attending weddings and formal functions like AD & D. If I were to wear a tube dress like the one below, I wonder if I am too outstanding.

Besides, I think I have tried a skirt with the bottom that has bubbles and I looked very odd. Perhaps, those of you who look good in the above red hot dress can look really stunning. Looks real good for Christmas and Chinese New Year too.

I love how this black and white tuxedo dress can have an instant slimming effect!

This pink summer dress doesn’t look suitable for a traditional Chinese wedding dinner but top it with a scarf and you are ready! It looks great for a Church wedding though.

I love this design as I can wear a jacket or coat over it during the office hours and take it off for a dinner after work!

What would be your favourite outfit for formal functions?
