Hi ilovemysphynx, I, too, have to dress up this Halloween for a huge costume party at a local 4-star hotel tomorrow. I'm not someone who usually likes doing the costume thing, so finding a nice costume for myself was a little challenging at first (as I'm a tough person to fit). However, I was able to find a fabulous costume that was warm, comfortable, and fits me great (and a cool, macho costume for the fiance, too) from an online costume store that my sister turned me onto called Costume Craze, here's their link:
www.costumecraze.com
Costume Craze has 1,000's of costumes that are reasonably priced, in many different sizes, and has cheap or free shipping (for $50+ orders). I liked the vast variety of outfits they have, too, much more than what you'd find at the local costume stores such as Spirit Halloween or Party America. Also, it's STILL NOT TOO LATE to order a costume or two from them to get in time for tomorrow...they have overnight shipping.
My fiance and I are going as Capt Jack Sparrow and Elizabeth from the Pirates of the Caribbean movie. My sister and her boyfriend are going as a barbarian/viking couple. Costume Craze has 100's of couple costumes in all genres and styles.
Hope this helps a little.
Like I said in my previous post, I usually hate dressing up because most of the costumes out there are pretty darn cheesy or very poor quality. The ones my fiance and I got are made by Disney so they are cool-looking and actually very nice quality for the price (about $40 per costume; the Elizabeth one was originally $100 but was on sale
