Gothic Lolita:-Probably the most common lolita style. The traditional blackxwhite scheme is very recognizable, but not all gothic lolita is black and white. This style incorporates the darker colors and themes (like cross motifs and veils) from Western goth into the more adorable lolita style to produce a very unique style that takes a lot of practice to perfect. So it's darker than sweet lolita, but much sweeter than Western goth. Most lolitas start off with this style because it much easier to find gothic items locally and it's very easy to coordinate.

Kuro Lolita:-"Black" lolita - like any other style of lolita but completely black. I'm not entirely sure why the style merits it's own name, but just a heads up this is what it is called. Kurololitas are often spotted with their lighter counterpart, the shirololita.

Shiro Lolita:-"White" lolita - any style of lolita done completely in white. This is a very tricky style to pull off because wearing floofy white clothing can easily lead to looking like a giant marshmellow, but it's very beautiful and striking if you can pull it off. (Sorry that some of these examples are more "cream" lolita.)

Sweet Lolita:-The second most common lolita style and definitely one of the cutest and most colorful. It has all the traditional lolita elements but in brighter colors (especially light pinks and blues) and this is where you'll find the most fluff and frill. This style is so essentially lolita that I can't think of much else to describe it

Hime Lolita:-Princess/himeloli is pretty much what it sounds like - lolita clothing a princess might wear. This style is very much inspired by Rococo (rather than Victorian) and is very fancy, with a mini-crown or tiara to complete the look. Sometimes the traditional loli silhouhette of a bell-shaped skirt is extended to a more full-length dress, usually with a slightly lower and squared neckline to balance out the fullness of the skirt (not a plunging neckline or anything). Jumpers can be found as well, but I haven't seen as many blouse/skirt princess looks. Overall though I'd have to say it's the most feminine and fancy of all the lolita styles, and often the most extravagent as well. Sadly many of the examples have been lost (this style isn't as common as it ought to be).

Country Lolita:-A subset of sweet style, with little straw hats and dresses in gingham, floral, and fruit patterns. Basically you look like a sweet lolita out for a picnic, so it is not uncommon to tote around a wicker basket or parasol. The print of the dress and the straw hat accessory are really the only thing that distinguishes it from sweet loli, and often the two are grouped together
Sailor Lolita:-Pretty self-explanatory, it's just a lolified version of the old sailor uniforms. The skirts have nautical stripes around the edges, the blouses have little sailor collars and ties, and sailor hats are worn in place of headdresses.

Classic Lolita:-Classic lolita is a slightly more mature version of lolita. It's not quite aristo because the loli silhouette is still present, but there are fewer frills and it's a lot less cutesy. Generally classic pieces are decorated with a few self-ruffles or some ribbons, but you won't find yourself swimming in lace and large bows. Classic lolis tend to wear darker or more muted colors (as opposed to bright pink or blue) and floral prints are common as well but aren't required for a classic outfit. What makes this style harder to distinguish is that it is right between sweet and gothic lolita - the dark reds and blues and even blacks can be confused for gothic style while the light florals make it look like sweet. What separates it from both is that it relies on an elegant cut or print instead of a lot of trim. The perfect style for those who love lolita but who want a more subdued look.

Punk Lolita:-Punk lolita is a really hard style to pull off because it treads a fine line between lolita and full-on Western Punk. Traditional punk elements are used - plaid, chains, spikes, deconstructed fabrics, etc. - but what separates punk lolita from traditional punk is really the fact that it's adorable and a bit cutesy. Good punk lolita tends to keep the bell-shaped skirt or the frilly blouse even with all the other more punk features, and lolita accessories are mixed with punk (for example, a lace trimmed spiked collar). This is the only lolita style where big stompy boots really fit, but honestly any shoes work for punk lolita so long as you have other lolita elements in your outfit. Though keep in mind you'll probably look a little ridiculous to real punks, so you may want to leave the frills behind for the Buzzcocks concertWalolita and Qilolita:-

Waloli - inspired by traditional Japanese clothing, including the kimono and less formal yukata. One option is a top or dress resembling a kimono with a lolita bell-shaped skirt. Often lace and an obi bow are added to make it more lolita. Oriental or solid prints are used for this style. Another far less lolita style occasionally put out by the brands is the lolita yukata, employing cuter prints and lace to try to make it look more lolita. I don't consider this to be very lolita but I'm putting it here just to have a complete view of waloli.

Qiloli - inspired by traditional Chinese qipaos (those cute little brocade dresses). Mandarin collars and frog closures with a Chinese print fabric usually identify these dresses. Often they are sleeveless but sometimes puffy sleeves are added to make them more lolita. Silk brocade would be the best choice for these but cotton is usually used. Hopefully I'll be able to find more examples soon, but this style is rarely done very well.

Gurololita:-This style also goes by "grotesque lolita" or "injured lolita". Any style of loli clothing will work for this because it's all about what you add to it (though it is more often seen on punk or goth lolis). Eyepatches, blood stains, fake bruises, bandages, and even slings give you that "broken dolly" look. This style can either look scary and gruesome or cute and all please-fix-me. Just don't overdo it, because you can quickly start looking like something out of a Marilyn Manson video ^_^;; Most of these examples are actually art because it's not a common style

Erololita:-Erololi is a more uncommon style that resembles normal lolita style on it is slightly more revealing and often has fetish elements such as collars, handcuffs, garters, and vinyl fabric. By revealing I do not mean exposing, the skirts are just shorter and the tops are a little lower cut, or ones that draw attention to the breasts. Corsets are often seen and usually without anything underneath (such as a blouse). The style ranges from ther darker stuff you see in places like "Torture Garden" to the adorable pastel frilly clothing of Kana. It's still appropriate to wear in public but it's usually meant for clubbing or going to concert. Despite being "ero" it maintains a certain innocence through frills, loli accessories, and a certain degree of modesty. It fits a more western definition of lolita (a sexual precocious - not promiscuous - little girl) but elegance and class is still important. Please remember that this is still a clothing style and is not porn.

Cosplay Lolita:-Cosplay lolita is to real lolita what school-girl costumes are to real schoolgirls. It's a little strange that someone would dress up like something you wear daily, but it's not really an insult or anything. However, lolita costumes tend to be cheaply made (since they're not going to be worn too often) and are generally less conservative than real lolita clothes (much like the naughty schoolgirl costume), so they can easily be distinguished as costumes. Often these outfits look very French Maid and for some reason seem to have a lot of cosplay add-ons such as cat ears or wings - things you wouldn't wear everyday. Sometimes poorly done lolita is referred to as cosplay because the poor quality of the outfit doesn't look like it was meant to be worn frequently.

Aristocrat:-Aristocrat is a more mature style, so I'm not sure whether it would actually be called lolita. But it is associated with it, simply because of it's old-fashioned elegance. The skirts are longer and they don't have to be bell-shaped, and he shoes and other accessories are typically less cutesy. It's what lolitas grow up to be - an elegant, refined lady.

Boystyle:-Boystyle is just as varied as lolita ranging from the cute little-boy style of kodonas to the more sophisticated dandy or aristocrat
