Are you doing figure/fitness or bodybuilding? If you are bodybuilding, I suggest that judges want plain posing suits. You don't want the judges seeing anything but your physique. On the other hand, for figure/fitness, multi-colored suits, jewels, etc. seem to be quite acceptable.
Hi s3, Im pretty new to the board, but would like to comment on your questions. I did the same thing for my first competition. I went to a local fabric store and wal-Mart and purchased the stones with fabric glue and did it my self. I also got some ideas frm some pictures frm a show a friend of went to and went added. I turned out pretty good. Here is also a webb site that I have purchased a couple of suits B-4 and she does a great job and alwasy have some suits on sale, lidiacontibodywear@lidiaconti-bodywear.com <lidiacontibodywear@lidiaconti-bodywear.com>Hope this helps
