Today a co-worker brought in a dress that she purchased for her wedding, but she never got married. She is moving and is trying to clean out her closet. When I saw the dress I thought it was beautiful and realized that it was my size, I tried it on and it fits really well. I am trying to decide if I should buy it to change into for the reception after pictures and first dance. The gown that I already purchased is a ball gown with a pick up skirt and a semi cathedral length train and is very bulky however I love how I look in the dress. The dress I am thinking about buying is beautiful chiffon with a plunging beaded neckine which makes me feel "sexy" it is much easier to move/dance in, needs minimal alteraltions and is only $200. My MOH and BM think that it is a waste of money to pay so much for my first dress and not wear it the whole night, they fell why have two dresses that I will only wear once. I am really torn on what to do. Any thoughts?
