Dress Etiquette?

[Morpheus]

One of the things that's rarely discussed is what are the do's and don'ts of what to wear when visiting a lady.
I know some consider it ok to wear a tracksuit but personally I would never wear one yet alone visit a lady in one.
The main reason I ask this question is I'm out now in very casual attire, jeans and a t-shirt and i have a notion to visit someone but would it be considered ok to arrive so casually dressed? It's not far off what I normally wear (shirt and jeans) but I still feel a little conscious with what I'm wearing. What do the ladies think, would I be ok?

I used to worry about this a little until I coped on that the ladies aren't expecting me to impress them. Manners, cleanliness, timekeeping and paying up front are probably far more important to the ladies than what a bloke is wearing. Of course many of us guys feel like we're on a date - hence the wardrobe dilemna.

I dress up for work and dress down for all other occasions. So while I think I look best in a suit, I always dress casually (but smartly, I hope) when visiting a lady for an appointment. Others have made a point about blending in - and this is part of it. I've walked by work colleagues on a the way to a punt on at least two occasions, and they haven't noticed/recognized me in my casual gear. By casual gear - I mean jeans, t-shirt or pull over, summer/winter coat etc.. the sort of thing I'd wear on a night out. Track suits I think should only be allowed if you're a family member of the Royal Tenenbaums!
