When asked for a definition for what Ero Lolita is, there seems to be as many views as there are respondents. Some (rarely those long into Lolita as a style) think it's showing as much skin as humanly possible, some say it could be something as subtle as using a certain fabric. I tend to disagree with both of these extreme views, and will now try to outline what I think it is. Yes, showing some skin definitely is a part of Ero Lolita, but not in the "bought this fetish Alice costume from Leg Avenue" -way. If you're going to show cleavage, cover everything else. If you want to show some leg, keep the top quite demure.
We've seen some quite differing takes on Ero Lolita over the years. Some photo shoots would suggest it's ero if you put on a corset and bloomers and parade around, posing in your underwear. But that's not Ero Lolita, that's just pin-up, in my opinion. Yes, even if you put that ridiculous Rococo-style cage-underskirt frame on top. An Ero Lolita outfit could comprise of leaving your blouse at home, to reveal some boob-action. Not enough to shout "hey, look at these puppies", but just enough to be suggestive. Or maybe it's those super high heels in your shoes, paired with fishnet or lace stockings?
Is it really a separate style, or just another variation of Sweet/Classic Lolita? Country style straw hats, gingham fabrics and picnic-basket accessories were all the rage at some point, but I seriously don't know if that should merit their own substyle all together. As cute, dainty and as rustic as these clothes are.
It's pretty much just sweet prints on a black background. Some people insist on making this into a whole new style and calling it Bittersweet. I really don't know what to make of it - maybe we should start calling baby blue Lolita outfits "Sky Sweet Lolita", while we're at it?
Stop the press! Lolita can be worn with Hime hair and tiaras or crowns! And here I was, thinking crowns and tiaras can be incorporated with Lolita without it automatically becoming a different style altogether. Not to mention that Lolita's supposed to be somewhat princess-y, with or without crowns etc.
