Shannon, you *know* I am going to love your outfit!! Taupetastic!!
Also, I have been thinking about pulling out my Long and Leans and today might be just the day to do that. Haven't worn boot cuts in an age, and I am liking the idea of a bootcut and my fuchsia jacket.
As for MIL -- I am sure she was having a rough day. She (and you!) have had a lot to cope with of late, and her mind is probably reflecting on many things. She is probably thinking over what is truly meaningful (for her) in her life, and perhaps had a moment where playing with clothes didn't rank in that list! Whereas at other times, I know she enjoys playing with fashion. Or she may have been feeling jealous of the attention you were giving to your own appearance (vs. to her). It is difficult to say. Either way, it wasn't kind, and you deserve a big hug!!
My family members think I am nutty, too, and while they are not cruel about it, they do tease me in a mostly light-hearted way, and occasionally they roll their eyes out of a sense of real annoyance (i.e. when I ask for a photo just before we head out the door). I don't do daily photos in part because I don't want to prevail on them too much (though I am asking for a tripod for Christmas so I can do it myself!) If they suggest at any time that what I am doing is foolish, I just laugh and agree, and remind them that it is my hobby and it keeps me in good spirits. To which they have to agree!
