I am happy to report that DS got engaged a few weeks ago! We are all very excited. He is my oldest son and is the first child getting married so I need some advice. They are looking at an April or May wedding so I have plenty of time. I just need some direction on where to shop and should I look for a long or short dress? The wedding colors are pale yellow and light gray (if that matters??) The wedding will all be inside in a formal setting. I am not sure how formal the dress should be?
