Well, another INTJ over-analyser here! (though I tend to score confusingly high on S, more so under stress, and especially on F too --- the opposite of Suz and Diana, if you will)
Like Suz described, I am happiest and most productive shopping on my own, and I really hate shopping at busy times like the weekends and festive seasons. It also doesn't help to get overwhelmed by the *packed* stocks during high shopping seasons, and I tend to prefer single-brand or umbrella-brand stores to multi-brand very often. In a multui-brand store, I am most successful when I go in knowing where or what to look at; else I quickly become overwhelmed. And I absolutely hate-hate-hate having a sales assistant start tailing me the instant I walk through the door --- I much prefer to be left alone to make my own decisions and be helped only when I ask for help! That's the introvert speaking.
In terms of style, as opposed to shopping, the introverted side of me can push me into wallflower mode when stressed. I just got over dressing in muddy shades for many years and only in the last couple of years have been trying to choose colours or even strong neutrals (like black!) that render me more visible.
When I'm feeling more happy and confident, though, I will dress with more exaggeration and visibility, sometimes a touch of whimsy, as Diana described, to offset the introversion evident in personal interactions. It also has a playacting quality to it --- fake it till you make it, which may be playing into the Intuitive side too.
The Thinking and Judging aspects both like to work to a plan, and often the plan is an abstract and long-term one for me. I feel like my closet isn't 'working' unless I am covered for every eventuality --- even if I can actually manage on most occasions. I have trouble with detail in my outfit (I can sometimes get stuck over the small missing piece, often an accessory) but am better able to get an overview of my wardrobe as a whole (seeing trends in colour, shape, silhouette, fabrication). I HATE not knowing what I am going to wear beforehand---especially stressful for an 'event' or for travelling, but even in the everyday, I ideally like to know what I'm doing and what I need to wear to best fit the next day the night before.
Though every so often I am also swayed by Feeling --- especially the tactile experience of textiles and shapes, and the influence of colour on moods. But I don't intellectually *trust* that feeling as much as I perhaps should... I am prone to telling myself it doesn't matter or isn't practical how I 'feel' about it if it works in theory! (Upside down from Suz's experience again --- I often have good results going with my gut, but I 'feel', haha!, that I ought to BE practical! And I don't seem to stop doing this no matter how often it backfires :-o) But the 'F' is strong enough, despite the T, that many of my closet mistakes are down to the 'feel' of the garment being wrong -- too staticky, too scratchy, too clingy, too stiff, too starchy, too binding...
And yeah, I'm driven absolutely insane by choosing until I have actually chosen, one way or the other! I *cannot* do last-minute shopping any more than I can do last-minute dressing --- and I much prefer to be able to rehearse every outfit for an event or trip even though it throws my closet into disorder and results in more laundry than strictly necessary (which the Thinking part of me resents --- I should be able to do this in my HEAD! no?)
