All costumes are available by the end of Act Two. I'm going to assume by "Chloe" you mean "Gwen", because Jessica's last outfit is her Hallowe'en outfit, and if you have Gwen's Hallowe'en costume then you'd have Jessica's too :)
To get the Hallowe'en costumes for Jessica and Gwen you need to have all the Hallowe'en decorations active in your room (Jack O' Lantern on the bedside table, coffin bed and witch poster) and then go to the dungeon in the evening.
Doesn't currently work, JSYK. Those were all I was missing as well and I did what you posted and the only option given to me now is to summon the character I defeated in combat.
Also, while we're discussing issues with the current update... where's the best place to post those for future ref? Discord channel I'm assuming? because ATM I noticed that the quick menu keeps disabling itself. If I click back it disables. if the screen changes from room to room or sleeping it disables. minimizing the window also disables it lol It's afraid of me! It keeps hiding!
One last thing, I like the combat system but is there be a way to grind? I lost my first battle using the MC and had to flee... came back using Chloe as the front and she whooped so much harder. Won in 2-3 turns both fights. So, I definitely need a way to grind considering I noticed only the frontliner gets the exp and if we get skills having the MC as support that will definitely gimp exp gain.
You have to do it in Act Two. For some strange reason, Jessica and Gwen don't really feel like playing dress-up whilst Gwen's dealing with her new situation and a war rages right outside the Manor gates ;)
The Quick Menu should be displaying permanently if you have it set to "Enable" in preferences. Make sure you don't have it on "Disable".
No way to grind right now, but I'm adding a "look for trouble" mode, hopefully for the next update, that will allow players to engage in non-district fights and gain EXP (as well as allowing MC to learn new skills from new recruits).
Bug reports and issues should be reported in the CK server, yes - makes it much easier for me to keep track of them that way :)
