Shop if you color-analyze Kate Moss she should never go anywhere near black - yet can you imagine her wearing Boden... A big chunk of my wardrobe has been and will always be black. Sorry, navy or charcoal will never look as high-octane chic. Nor will brown.
At this stage, you can explore which ones of your new colors you really enjoy wearing. Some of them will look good on, you but you will not like them (I look good in dusty pink and mauve but cannot bring myself to love them). Some of them will look fabulous and make you feel fabulous. When you get the elements right, with the rest you can just ask whether a new item will fit in. And you can always start with tops or accessories and pair them with your old stuff. Put the items you are not sure about in storage - I'm going to rescue an old floral-on-black chinoiserie jacket from the cellar as soon as the weather cools down and take down lots of summer dresses I'm not all that keen on.
Also feel free to skip a season / wait until sales time - burgundy is difficult for me, the coolest ones might work but I've always felt frumpy and wilted in it... I'm actually already looking forward to clear and bright spring colors (but then fall is so not my season)
I posted a few pins recently that feature gray sweatpant chic. You dress them up with heels, ankle boots and balzers these days (party outfit conundrum solved?)
Hopefully iirc Ms Picardie has either written for Vogue or is related to somene who used to be important there

Oh and there is a little bit of me in most YAWYW chapters too. But I really hope I won't ever have to revisit the mom jeans stage any more
