In a crowd of her fairy sistren Emma tends to stick out.  She's "tall" for a fairy and looks rather athletic compared to most.  Emma also tends to be rather loud and boisterous, for better or worse.  She's also gained a reputation for being "clumsy".  It isn't that she tends to trip on her own feet, as she has grace in spades, but rather her talent for breaking things tends to get Emma into trouble (and make more work for her fellow fairies!).
