Not Carter, but also someone who has bought plentiful for a fantasy lifestyle.
I can see why you'd want to get all 3 pieces. So gorgeous! I really really really love that jacket, btw.
So you say you can wear that jacket to work in winters, right? So where is the problem?
Summer - wear the shell & skirt as a stylish business suit for important meetings and also wear separately.
Winter - Wear the jacket too - with the skirt & shell or even on a simple pair of black trousers + white button down outfit.
The reason I am enabling:
1) It would be buying for a fantasy lifestyle if you "didn't have an office to go to". You go to an office; you sure can dress in formals sometimes
2) These are classics. Will never ever go out of style, even if you wear each piece no more than 3-4 times a year
3) My winter & summer wardrobe doesn't overlap. Does yours? I can't wear my leather moto jacket or even denim jacket for 8 months a year, but I *can* wear jackets for 4 months, so I do buy them. I see no reason why buying that jacket is relapsing into buying for a fantasy life/fantasy climate.
PS: How warm is your climate, btw? Warmer than mine?
