Sigourney Weaver has grown out her hair a little from the usual cropped cut she has worn. The wave she naturally has, as seen here along the front could be the reason why she prefers to keep it shorter and that's not such an alien prospect.
Shorter lengths will be popular this Fall and are already returning as Summer probes us to do. Not to be "alien"ated from fashion, Sigourney Weaver has a great style that's mainly all-one-length with some slight tapering all along the edges for feathering her style.
Though she has sported it much longer, Sigourney Weaver has worn her thick mane in a short hairstyle for a while now, foregoing the weight and maintenance, that hair of her density requires. Here she has cut her coiffure into a bob type style with sweeping side bangs that shouldn't leave her feeling 'alienated' from the trends of today.

Featured here from the recent premiere of "Infamous", Sigourney Weaver once again amazes us. Through many roles, Ms. Weaver has worn her hair short and we haven't seen it at this length for numerous years. Many times an actor's hairstyle is kept in a certain style according to the sequel he or she may be involved in. Though we would never have alienated her according to her short haircut, this simple all-one-length style is quite feminine and is beautiful on Sigourney.
