I am certain that Jeanette wasnt intending to sound selfish with this thread. Those of us that are native English need to remember that there are some on the forum who arent as fluent in the language. Add tat to the difficulty of conveying emotions and feelings in the written word and there can certainly be misinterpretations.
What I feel Jeanette was trying to say is that the wedding was going to be a challenge seeing all of the pretty dresses while dressed in drab. I can relate in that seeing pretty women in pretty clothes sometimes makes me a bit jealous. So I can imagine being at a wedding if you really like drssimg to the nines.
