Oh that's a great thing! Thank you for posting that! Can you post a picture of the whole piece too? If it isn't in our system yet, we can add it and give you credit for the photos!
This tag shows you one of the numbers I talked about in my answer to your post about RN numbers. 54293345/9902 is the Style/Item number. The 9902 is for the size. The rest before the slash is for the slash is the style number (Item number in our system.)
This tag also gives you the line name! We love when we find those! Spring Bloom was released in Spring 1997. If you let me know which piece it is from the line, I can get that item entered into the system. I would also like, with your permission of course, to add this photo of the size chart to the line page. We have been working on compiling size charts for the various years but it is taking us some time. Photos like yours are invaluable!
