Making the Cut
A stiletto stalks through the bushes and reveals... Derek J! Let the wedding wig styling commence. Of course there is a lot of pressure on Kim's wedding wig being perfectly coiffed for the blessed event, so Kim wants to put her fears to rest by getting it out of the way.
Derek J doesn't understand why they can't just hold off until the wedding day when they actually have the dress. It's here that Derek J made an egregious error -- Never, ever question the bride. Has he never encountered a Bridezilla before? Because there is no more dangerous creature in the animal kingdom. It doesn't matter whether it makes more sense to cut the wig later. You do it whenever the bride tells you to or feel her stressed out wrath.
Luckily no one was injured and things proceeded as Kim had planned.
You are absolutely right that Kim should have told Karen she didn't want her at the catering thing, but the results would have been the same or worse. It was horrible that Karen's hissy fit kept her from supporting her daughter and meeting the in-laws. It was vindictive and childish and I wouldn't have taken pictures of those dresses to save my life. I'd tell my mother to wear whatever the hell she wanted but not to expect to be in any family pictures unless it's appropriate.
