Yes

U'd be targeting a pretty niche market tho.. if u're planning on taking this far, u might wanna consider bringing in *quality* stuff, not the cheapo material sort.. eg. authentic jap schoolgirl uniforms fetch a very high price + high demand... the biggest customers will probably be frm the upper-middle class & above, so u could consider abt bringing in gd quality western role-playing clothes too, like corsets - my more well-to-do female friends have complained to me about the lack of gd corsets here .. and these are the big buyers u'd wanna net.
