When I think of see through materials, the iconic trend would have to be YSL's 1969 sculpture gowns. Since 2010, this trend was popular among all styles, in 2011, Harajuku girls mainly use it with contrast materials.
Combinations of different materials have been introduced by many big brands since the Fall of 2011, and it soon became trendy for the Harajuku girls, who are really good at pulling it off. The denim and leather match was particularly popular.
2011 Tartan was big among boys and girls in Harajuku, men wearing kilts, and the women love tartan coats, vintage style is preferable.
Everybody knows this trend last year, it was very popular before the earthquake struck Japan, but then did not seem to fit with the mood of the country. But the Harajuku girls brought it back to lighten up people's mood.
This look was seen in many big brands in A/W 2011, Japanese girls generally like oversize knits to contrast their tiny frames. Last year, big sleeves were particulaly popular, with beige, camel, and grey colour to soften it up.
White tights appeared in Harajuku from late 2010, and became more popular in 2011. It represents the lolita spirit which is always popular in Japan, it was also a big element in Bottega Veneta 2011 Fall collection.
The 'collar trend' was probably one of the most dominant trend last year. Who knew a tiny collar could make such a difference to one's style! Some say the collar trend in Japan began when Princess Diana visited Japan in 1986.
Following the boys, platforms was big for girls as well. Platforms are always trendy, but you can see a lot of Converse, Dr. Martens platforms last year.
2011, vintage glasses were very popular. They name girls that dare to wear big old school glasses "Akiba Girl" in Harajuku.
Cool, simple, chic, and cheap, the American Apparel tote bag was very popular among the Harajuku girls, especially the younger crowd.
