Anyone wearing this type of stuff should be disqualified off the stage.
Yours is the opinion of many people who are yearning for the old days when competitive bodybuilders wore posing suits that actually had more than an inch of cloth covering them up. Times change. With each decade competition posing suits have become increasingly briefer. Frankly, today pose wear is so brief that there really is no need for it at all (goes for the gals as well as the guys). At best, they hide what is lacking in them more than covering what little modesty remains.
When all is said and done, many people still weakly cling to the old Victorian ways.
