I'm going to preface this by saying that I know almost nothing about vintage clothing or fabrics, so I'm really sorry if I sound like an idiot. I was recently gifted with a pink tea length party/prom dress, with a beaded bodice and matching short (bust-length) short-sleeved jacket. It belonged to a friend's grandmother, who was a dancer and apparently quite the fashion plate! I believe it is from the 50's, due to the bust shelf and general style, but I could be wrong. The label says "Junior Theme New York" but there is no information about the fabric content, and I don't know enough about fabric to be able to accurately ID it. The lining is a silky, sturdy fabric with a visible weave, and the outer layer is a slightly stiff, sheer fabric. I want to call it tulle, but it doesn't have the open weave I associate with tulle. Anyway, it's the outer layer that has a few problem areas. There's some yellowing, which I don't think is fixable and which is overall not a huge problem -- it mostly just gives the dress a more peach cast, rather than the brighter pink it probably was originally. The real problem is that there is some splitting/shredding of the outer fabric at the armpits (not very visible when it's being worn) and one small split in the skirt. None of these problem areas are very visible (I didn't notice the hole in the skirt until I looked closely), so my main concern is how to prevent them from getting worse. I'm reasonably handy at normal mending, but I don't think sewing the split would help, since the stitches would be highly visible, and it's possible the fabric would tear around them. I have a feeling it's probably sacriligious, but would using something like Fray Check on the hole in the skirt have any benefit? I'm not a collector; I want to be able to wear this dress, possibly for my wedding. At the same time, I don't want to ruin it! Basically I'm looking for a solution that will allow for light wear and hopefully slow the deterioration of the fabric. Can you help a girl out? If it helps any with the fabric ID and care, I did handwash the jacket (which has the same sheer fabric) in cool water with no discernable ill effects.
