As a redhead, I don't care if it's cliche or not, greens are my especial favorite color to wear. I wore green to my first prom (bf was a hs senior to my little junior self at the time) and I went for a purple dress my own senior prom, because purple is my favorite color. Well, I tried at least. I brought about 8 different purple dresses into the dressing room and they all looked good with my hair and coloring. I ended up bringing a red one in too because red is the bf's favorite color, though I didn't think my red hair would work with it....Damn thing ended up looking the best on me.
For the sake of relating myself even more to Claire, I'll mention that I also own a blue dress that does indeed look surprisingly lovely on a redhead. But green will always be my favorite color on me with a nice brown coming in at a close second.
And just as an aside, when the interns were all introduced, I'll admit I had an inward moment of "Ugh, talking background characters," but since then I'm delighted Claire was the one to join the main cast and I'm loving her more every time we see her
Well, let's just say I'm not partial to grown women in frilly princess dresses and leave it at that.
EDITED just to add that Claire never exactly got to be a little girl in a frilly princess dress, so I'll pardon any appearances of her in it in later strips, because we all KNOW she bought that one too
