Lynne is trying on dresses in front of George and she asks him if the one she is wearing is too long. She changes and then asks if her current dress is too short. George tells her that both are great and adds that that’s the long and short of it.
George and Lynne are getting ready to go out. From experience, George knows that Lynne will always try on a number of dresses before making her final choice so has not started to get ready himself, but has stayed in his gardening shirt.
Lynne, despite buying a lot of clothes over the years, still does not know the difference between a dress and a skirt. You would think that after all this time she would know, but no, she doesn’t.
The second dress might be too short for the dinner she and George are going to, but unless the first dress is getting caught under her shoes then it really can't be too long. In fact, dresses that drag on the floor have been the style. Maybe that is a little 'out there' for Lynne.
