I was just wondering if it would be considered tacky if I took my niece shopping for a dress and accessories to wear to my wedding. I really would leave it up to her to find something formal enough for my wedding, but I really doubt she would pick something appropriet enough for the occassion. I am basing this off of the fact that when she went to my brother's burial earlier this year she showed up in a pair of pajama bottoms, a camisole tank top and a zip up hoodie.
