Attire

There are 12 different outfits for Sybil to wear in-game. Most of these are unlocked by beating a Time Trial crystal present in every major area; some are given when Sybil obtains a major upgrade, and reflect which upgrade(s) she has.
==Basic Vest==
This is the outfit Sybil is wearing at the beginning of the game.
It includes a black button-up vest and a small white cape.

==Big Pants==
This outfit is added to Sybil's inventory when you check the "Give Sybil Pants" option in the Options menu.
Equipping this outfit will give Sybil large, baggy pants, golden under the knee.
==Professional==
"Professionalism"Unlocked by completing the Time Trial in Castle Sansa.
"Professional" gets rid of Sybil's basic vest and cape. Instead, she's wearing a full-body black unitard with a white bolero jacket, gold armbands on the upper arms, and black fingerless gloves. The unitard has holes on the sides of the thighs, allowing some of Sybil's fluffy fur to pop through. 
The only part of the outfit that is the same from the Basic Vest is a small gold bracelet on Sybil's right wrist. On the Basic Vest, there are bracelets on both wrists, but the left one is removed for this outfit.

==Sun Greaves (outfit)==
Obtaining the Sun Greaves powerup will automatically give Sybil this outfit.
It simply adds golden greaves to the Basic Vest outfit.
==Cling Sleeve==
Obtaining the Cling Gem powerup will automatically give Sybil this outfit.
This outfit adds a black sleeve to Sybil's left arm, with a blue gem on the back of Sybil's hand and a gold bangle. It also includes the Sun Greaves in the outfit.
Obtaining Cling Gem before Sun Greaves will not auto-equip this outfit, but it can be selected from the "Attire" menu. Sun Greaves will only be an aesthetic addition, and it will not grant the ability until obtained normally. This will also cause the Cling Gem outfit to appear above Sun Greaves in the "Attire" menu.
==Soldier==
"Chivalry"Unlocked by completing the Time Trial in Empty Bailey.
This outfit replaces the basic outfit with a white robe and gold armor.
==Guardian==
"A Guardian"Unlocked by completing the Time Trial in Sansa Keep.
This outfit replaces the basic outfit with a white leotard and a red half-cape.
==Sol Sister==
"Devotion"Unlocked by completing the Time Trial in the Dilapidated Dungeon.
This outfit replaces the basic outfit with a nun's outfit.
==Classy==
"Class"Unlocked by completing the Time Trial in Twilight Theatre.
This outfit replaces the basic outfit with a top and pants. Sybil's horns also gain another point that expand downward toward her ears.
==XIX==
"Nostalgia"Unlocked by completing the Time Trial in The Underbelly.
This outfit replaces the basic model with the model from an earlier version of the game, including different hair.
==Sleepytime==
"Sweater"Unlocked by completing the Time Trial in Listless Library.
This outfit replaces the basic outfit with a white sweater and socks, one thigh-high and the other at ankle's height.
==Bleeding Heart==
"A Bleeding Heart" Unlocked by completing the Time Trial in Tower Remains. 
This outfit replaces the basic outfit with a purple dress with yellow details, as well as removing Sybil's horns and adding yellow stockings and a flower wreath on her head. Her tail also becomes more fluffy near the end and gains a purple tint.
