I'm at the opposite end of the spectrum from most women in that I find clothes shopping tiresome because I usually know exactly what I want but can't find it - having a planned wardrobe fits my philosophy well but also entices me to buy clothes because I can see where the gaps are. Mostly I love being able to get dressed for work each day by just pulling out this week's jeans and a random top from the season's half-dozen that are all hanging ready in my tiny wardrobe :)
ETA: I spent this morning packing away my winter wardrobe, then tried reading some colour analysis webpages and ended up totally confused! I'm a darker autumn (warm skin, chestnut hair, brown eyes), but I'm not sure exactly which type - and that makes a big difference as to whether I should wear black near my face or not. I don't trust myself to make the right call here (I have lots of black tops in my wardrobe!) so I decided to pay to get analysed. I think it's a worthwhile investment if it helps me build a better capsule wardrobe.
