Juvia is a character of change. I feel she has some of the best progress over the series, physically and emotionally. She really does have the most change looks wise over the course of the series, more than any other character. While Lucy may change her clothes every arc, Juvia is changing everything. I feel her outside really does reflect her inside. One might assume this is a shallow assumption however it is something Juvia points out herself, calling each look a "version". This will look at her "versions" with other note-worthy outfits being listed after that.
Juvia: Gray-sama! I've been upgraded to Juvia Ver 2.0.
Gray: Since when were you some kind of machine?
Juvia: From This point forward, Juvia's going to enter a new age!
This is the initial look of Juvia and is seen up until the end of the Tower of Heaven arc. Juvia wears her hair long, down to her shoulders with tight curls at the bottom. I feel her hair is the darkest shade here. She covers the top of her head with a Russian Cossack hat. She wears a knee-length navy blue coat with golden buttons adorning right side. Covering her shoulders is a darker navy shawl with a teru teru bozu doll hanging from it. A light yellow/brown fur trim can be found on her shawl and at the end of her sleeves. Juvia has a plain black belt with silver buckle across her waist. Based off of screenshots of this outfit from the Tenrou arc, it can be assumed Juvia dosent wear any clothing underneath her coat (other then assumed undergarments). For her lower body, Juvia wears long-heeled, dark brown or black boots. Her boots are long enough to wear her coats covers the top part of them. I find The color seems to depend on the arc and the animators.
This is the second big look for Juvia. This seen as a big step forward and her "rebirth" as a member of Fairy Tail. She wears this look up until she returns from Edolas. Her hair is cut to about chin-length with some minor layering. Her hair here is rather light colored i find. Her hat has changed to a what looks like a pillbox/tricorn hybrid with white and blue coloring. There is a light blue spiral in the middle of the cap. (if you know what that hat is called please tell me ;.;). It looks like Juvia is wearing a dress however i feel its outfit made of several pieces. She has a sleeveless, collared white shirt underneath a low-cut spaghetti strap looking tank-top. It is dark blue with some light blue trim along the sides. Attached to her collar is a light blue broach/ribbon with the fairy tail logo. Adorning her arms are 3/4 sleeve length white gloves with some blue trim. Starting at the waist, she has a knee-length dark blue skirt with some pleating. Covering it is a wider, knee-length skirt that is white in color. It is pleated with blue trim along the bottom. Lastly she has flat boots that come up the bottom of her knees and are white in color. Along with her gloves, they have blue trim down the middle.
This is the third look of Juvia and is a retake on her classic look. Trying to recapture her old look and the look of her Edolas counterpart, She wears this up until the Grand Magic Games. Her hair is back to shoulder-length hair with tight curls. She covers the top of her head with a Russian Cossack hat. She wears a knee-length navy blue coat with golden buttons adorning right side. Covering her shoulders is a darker navy shawl with a light blue fairy tail broach replacing her teru teru bozu. A light yellow/brown fur trim can be found on her shawl and at the end of her sleeves. Juvia has a plain black belt with silver buckle across her waist. For her lower body, Juvia wears long-heeled, dark brown or black boots. Her boots are long enough to wear her coats covers the top part of them. I find The color seems to depend on the arc and the animators.
This is the fourth and one of the more recent looks of Juvia. This is what she looked like primarily through the Grand Magic Games. Its a twist on an old classic so to speak. Her hair is still long but with her curls straightened out, with the ends being slightly wavy. She keeps her Russian Cossack hat look but it now dark colored with some white fur trim along the bottom. She has a golden butterfly brooch adorning the side of it. She wears a knee-length dark colored coat with four golden buttons adorning the chest. She no longer wears a shawl but the collar and sleeves of her coat have white fur trim. Juvia's belt has changed from black to brown with a silver buckle. She has traded in her high-heeled boots from some flat, long brown boots that are partially covered by her coat.
This version will be added once i have seen a colorized picture of this look
This section will examine other looks of Juvia that are short-lived or might be considered situational. In general, Juvia's looks stick to a general theme of curly or wavy hair and hues of blue in her wardrobe.
This outfit is worn briefly when she follows Gray and party to the Akane Resort. To my knowledge it has not been worn since. Juvia wears her hair long, down to her shoulders with tight curls at the bottom. She wears a knee-length, blue dress with halter straps that go around the neck. The dress is backless and is rather low-cut, revealing cleavage. Adorning her neck is a rather large gold fairy tail necklace. While it cant be really seen, i assume Juvia is wearing some type of high-heel, most likely blue in color.
This is a look that Juvia briefly has during the Tower of Heaven arc. This sudden change in look is due to Vidaldus Taka's magic. Compare to all other looks, Juvia's hair here is the longest, going almost as low as her butt with the ends being wavy. It should be noted that her eyebrows appear slanted here and she has some dark lipstick on. Her skin also looks much paler then usual, almost as white as a ghost, perhaps mirroring Taka's looks. She wears a necklace that i believe is intended to be studded or barbed looking. She wears a revealing tank-top that is not only low-cut but shows her mid-riff off. The tank-top also has some corset like qualities. Her midriff bears a type of tattoo. She wears low-rise pants that have a slightly reflective material, perhaps leather. She holds her pants up with a white belt with a simple gold buckle. On her right wrist she wears a spiked bracelet. As for her shoes, it would appear shes wearing some kind of heeled white boots.
Over the course of the series Juvia seems to stick to three types of swimwear, all bikinis. The first made its appearance during the fighting festival arc and is a simple blue bikini with white polka-dots. The second time she appears in a bikini is training before the grand magic games. This bikini is light blue with some white-ish blue fringe along the halter-top and the bikini-bottom. The more recent bikini Juvia is seen in is in the naval battle during the Grand Magic games. The bikini top is haltered once more with white fringe leading down into a small tie. The bikini is blue with white polka-dots. The bottom has a white band across the top and then it tiers down into a little skirt.
