You'll be fine, though from time to time you do get less attention compared to those with a Len or doing the same series. I know that when I was Miku in the Venomania outfit I got attention while cosplaying with my Fiance, then when she changed no one came to me. She had been my Kaito that day. I think it really depends on the character/series in general though.
