Good points, Thistle and I can't believe it's almost baby time!
I have been trying to do more honing becaue I know I'm just not wearing some things.
One think I've learned is that I need to NOT think about spring and fall as separate wardrobes. I hadn't really done that supe- intentionally, but I love "seasonal" colors and was about to hold myself to too much of a seasonal color palette. The downside of that would be that if I have things I think are ""waiting" for fall, or spring, as seasons, instead of just temperature-rating, then they sit for a year, and meanwhile I, or styles, or my tastes may change, and stuff is just taking up space.
I already accept that since I'm cold-natured, I do collect warm sweaters that are mostly for Nov-Feb. Even, there I'm trying to do more with layering to extend the months of wear of some items, but the fun factor of warm thick sweaters is high, so I accept that I have a "winter wardrobe" and will try to keep it partly "timeless" (or moderate longevity) plus budget for trend/replacements.
This is an issue for work clothes, which would tend to be more of an investment, but also casual clothes. Due to my work schedule, a couple of months could go by without my being able to do much non-work events, or very many so I can potentially miss the window to wear items that are too tightly seasonal in feel or use.
The only difference it makes in my approach is to really ask how I "feel" about when I would wear something, and if I feel it screams a limited season, I really ought to re-think (exceptions, balance, moderation, of course!) . Second, I'm finding a few colors (real colors, not gray!) that swing both ways and might not be what I thought. Third, I'm really reviewing my accessories to earn their keep as the items that help skew seasonal--put the orchid and white in the scarf, or the lovely fall tones in the belt and necklace--things like that. Then, I will not "wait" until Feb to wear the orchid cashmere. I might not wear it as often, in Dec, but again it's the concern that only by wearing things can I re-assess whether they are still working, whether I should stay in that direction. Otherwise I find I'm surprised if the item I "saved" looks off, somehow.
The trick is to find the balance between the wearing/ assessing approach, and the Keep-something-back for a refresher approach.
