Chelsey, I guess it would kind of depend on the situation that caused her to drop out? Did she have a personal conflict, family tragedy, etc that prevents her from coming, or no longer being able to afford to come? If this is the case, I think you could still give her the gifts to show her that you truly wish she could be there and that you support her back as a friend in her tough time. However, if she has just decided to back out on you, without being up front with you about her reasoning or simply because she's no longer a close friend, I would have to say I wouldn't give her the gifts. The dress is a tricky situation though... if you eat the rest of the cost on the dress, you could always try to sell it. Will the bridal shop charge you anyway if she doesn't pick it up? Or do they keep it and she just loses her deposit on the dress?
