I did a clothing tracking "thing" last year, and used colours to identify what clothes I wore in what season. So it's easy to see what happened here last year, and thanks for the excuse to actually look at it somewhat analytically!
The conclusion: I have six clothing seasons, with sub-seasons, defined by footwear (which indirectly includes amount of skin I can show) and attitude.
Summer: Open toes, Short sleeved tops, sweaters, toppers may be worn/needed in AC or evenings (esp denim jackets). In the middle of this is "hot summer", when the sandals are more open, sleeveless tops, as little fabric touching as
possible. Lots of dresses (July/Aug) (mid June to mid Sept)
Late summer/early fall: Time to put the toes away, still ok to bare skin (ankles), toppers worn outside esp in the morning and late afternoon (mid Sept to mid Oct)
Fall: Long sleeves, socks, booties, light coats. No snow. (mid Oct-mid Nov). I love dressing for fall, and am so sad it's apparently only a month long. I could start dressing fall-like earlier, but my toes object strongly to being put away when they don't have to be. This is a very funny season here, you'll see a massive variation in what people will wear on the same day. I'll be in sandal booties while my neighbour is in high boots.
Winter. Sigh, here it is. Snow time. Warm boots, coats, lots of long over lean so my lean can be tucked into boots. I break this up by trying to wear "festive" clothing the 2-3 weeks leading up to Christmas. (mid Nov to early April). In the middle of this I stick:
Deep Winter: My heaviest sweaters, lots of black and navy (Jan to early March)
Spring: early April to mid June: Snow is gone, out comes the booties again, morphing into oxfords, loafers. Socks get shed, ankles get bared. I love 3/4 sleeve sweaters at this time. I used to get caught with "nothing to wear" in spring because I always discounted it, but eventually got smart when I realized there was actually a couple of months when I wanted to dress like spring despite the weather. I will wear some of the same things in fall and spring, but really, by spring I want lighter colours and fabrics so even if the fall things are right for the temps, I am looking for something different.
In terms of storage, I pack away my winter clothes/footwear and my summer clothes/footwear. The rest tends to stay out, as there is always a random hot day or cool evening when you want something out of "season".
