Sorry about the extra long weekend. For anyone that is curious, XCOM 2 is amazing and you should get it if you're at all interested. It's hard, though. Be ready.
Today I started putting the bikini contest into place. In May, a notice will show up on the beach about a contest being held throughout the summer, where you can sign up by calling in (as long as you're not at femininity 10 or lower). This, in and of itself, is a chance to influence femininity, but the important part happens at the beach on June 2nd (which required a specific exception to the weather system to make sure that it's sunny that day).
Once you get to the contest, you sign in and can meet the judges. The judges have specific interests that they will rank you on during the actual contest, in addition to what bikini you wear. Some judges may like big boobs, but not too big. Some judges may like a certain length of hair. Stuff like that. For the first round, what the judges like is set in stone, but for future rounds, the judges tastes will be randomly assigned, but you'll have advance notice as to what they are. Consider the first round the "amateur" round, and subsequent rounds will let you work towards a certain look.
Anyway, you can meet the judges, and maybe learn what they like or don't like, but more importantly, you can try to influence whether or not they'll help you win. Some judges respond to bribes, some to sexual favors, and some judges will decline your attempts and mark you down for it. It really depends on their personality.
The actual contest will give you points on what you're wearing (one-piece = 1, bikini = 2, skimpy bikini = 3), as well as how much you match the judges ideal. If a judge like big but not too big boobs, for example (say, DD), then if you match their ideal, you get lots of points, up to a maximum of 8. If you don't match their ideal, then you get less points. As in the previous example, if you have B cup breasts, then you'll only get 5 or 6 points.
The goal is to win, but the top three contestants get to move on to the next round, which takes place a few weeks later. There'll be four rounds in total, with cash prizes for each round. If you manage to win the final round and never cheated, you'll be offered a job as a model (currently a nude model, since model isn't coded in yet), regardless of whether or not you actually qualify for it.
Naturally, participating is a good way to raise your femininity, and winning can help your Natural Charisma. And maybe you'll meet someone that wants to win just as much as you do...
