It's all in how you say it

Ok, so today I wore a skirt, haven't done that in a while. I didn't like my shoes for a bit, then I didn't have any nylons, so I couldn't wear a skirt.

So today I come in to work, getting myself a cup of tea and I had someone say "you look nice today". WTF is that about? Why do you need to add "today" to the statement, if you say "you look nice" that's all you need to say! Adding the "today" just makes me feel like normally I look like a bum but today I look good.
