It was my first convention, so I only wore a costume for the Masquerade. I was planning to wear an Arwen's Angel Dress costume, but I ran out of trim and time to finish it (and to this day, it still isn't finished, because I know more about sewing and constructions and I see too many imperfections in my old work), so I went with the nicest costume I owned (and it is still one of my nicest nowadays), my Arwen's Dying Gown (also known as Beach Blond Arwen).

The next was Maral Agnerian a.k.a. Sarcasm Hime; her costume was simply breathtaking.

I was truly impressed by their costumes. I absolutely loved them. You can't tell from the picture, but, for instance, there are rows of seed beads down the petals of Maral's costume. I though they should win, but apparently, the judges thought their costumes were bought, or so Maral told me when I met her at Otakuthon last year, where she and Dawn were judging the Masquerade. It should be mentioned that two of Con*Cept's Masquerade judges were Stargate SG-1 (1997) Peter Williams (Apophis) and Douglas Arthurs (Heru'ur). They didn't know much about costume making, but the skits that made people laugh won (including, surprisingly, one about a Jaffa and an SGC soldier). Also, Masquerades usually follow the International Costumers' Guild Competition Guidelines, but they just gave first, second and third places.
But that's OK. I was happy to be there, I enjoyed my first experience at a convention, I made friends and got to see gorgeous costumes.
