clothes.. clothes and more clothes

Yes, I sound like an airhead, but this is my first professional type job, so I need to look good. I have never needed work clothers before, and this is like the UN for heaven sakes! I was in the bathroom for like the past two hours, trying on different combinations of clothing. I have 45 items, which will all fit in one suit case- I know I tried it-, but I still need a big suitcase for my otherstuff.I made sure that each shirt can be worn with more than one bottom, and vice versa, to help give me more wardrobe choices. I have to admit though I kind of cheated a bit by saying this shirt goes with my jeans and my jean skirt(s), as opposed to goes with my jeans and beige pants. Is three pairs of jeans and three jean skirts too many? But each has a different property and purpose .. like one pair of jeans has cute embroidery on the legs, and one jeans is for looser fitting tops, another pair are for tighter tops. Similar things with the skirts. I mean I do need some more casual clothing for weekends and traveling. I wonder if I can wear jeans at Unesco? It's not such a concern in Vienna, because I will be attending classes, and Helga doesn't actually have an office. I wonder if I will get my own office or desk at Unesco? But then again, they wear black in Paris. Although I should point out this does not include my bathsuit, pjs, or undergarments. Do you think it's too much if I bring two coats? My shorter blue peacoat, and then my long beige suede one with fur on the neck and wrists? I also think I need a pair of black winter boots. The shoes I am planning on bring are a pair of black dress shoes, my blue winter boots, my beige uggs, and my black backless pennyloafers (and then the black boots when I buy them). These all goe with my wardrobe pallete of beige/brown, blue, white and black, although there is some colour in there. If anyone has any suggestions of clothing items or other things I should bring, please let me know. I know it sounds like I am bringing a lot of clothes, but I mean I have to pack for the spring a bit too... plus in Austria it's colder than Paris.. it's like plus 1 or 2 in February, but in Paris it is like 7 or 8 degrees. Plus if I travel to Spain or a warmer climate, I'll want to have wearable outfits. I am not even bringing a 1/4 of my wardrobe, maybe even less, so this will be a shock in itself, but hey, there's always Milan and Paris, the fashion capitals. and London. Look out the shopaholic is going abroad! And thanks to Stacey and Clinton, I know now what not to wear, well maybe I have a better idea anyways. God, I never realized what I clotheshorse I am!
