[QUESTION]

Yes, I forgot to mention something. Regarding "one of the winners in the 4th contest," she is wearing armor, but it's not very good. Those "curves" are very clearly emphasized, which would be convenient for the enemy to strike precisely at them, as it's a vulnerable point, and the shape of the cuirass doesn't help deflect the blow. In other words, it actually encourages the blow to slide, but it will slide into the chest between the "curves" and cause even more damage. In other words, regardless of gender, armor has never been designed with protrusions. It should be smooth and sloping so that blows slide off, rather than being held on the body.
