Easily option 5 and also, you are acting like a moron. There are practically no job interview situations where time spent worrying about your attire beyond what is necessary for layman (not styleforum) appropriateness would not be better spent preparing for the substance of the interview. You are stressing about something that only makes a difference at the margins and has a much smaller chance of impacting your interview than other things you could be doing.
Good point. There is reaction and over reaction, I reckon the second one applies to me. To be frank, Im quite stressed about the upcoming week and not thinking clearly. I will just go by option 5 and wont break my balls over it. In future for other interviews, I will not leave it all so last minute and up in the air.
You may need advice on how to feign sanity for the next few days, so here it is: Buy the first OTR suit you find that fits "OK". I know this is StyleForum, but buy the danged thing at Jos. A. Bank or Mens Wearhouse suit if you have to. You are interviewing for to be an R&D manager, not a clothing designer. I promise you that wearing a slightly ill-fitting suit for the interview will not be a strike against you. Get the store to rush the hemming. Make no other alterations - you cannot take the risk that something gets screwed up in your short timeline. That's it, that's all you need to do. You will be fine if you do this. Or at least, your wardrobe will.
Thanks for your commentary. I will go to Desert Hills outlets tommorrow anyway, my wife wants to visit the Prada outlet there for some new boots. If I find a reasonably well fitting suit at the BB or Saks outlet, cool. If not, I will just fly with one of those listed for option 5.
