Leslie Belle Blouse & Skirt Set Size 12 Vintage

Here I have a set of clothes made by "Leslie Belle" The blouse says it is size 12. I also took measurements of both items. The bust measurement across it I got 18 1/2 so it will fit a 37 inch bust. The length is 23 1/2 inches. The sleeves are 10 inches long. The skirt waist I measured 13 inches across so it will fit a 26 inch waist. The length is 24 1/2 inches. The skirt does not have any tags in it. The blouse unfortunately though is missing 1 button which is shown in the pictures. This set has been stored in a tub quite awhile. This was my moms set. I don't see any stains, or tears. The set definately needs a ironing though. It is made of 100% Polyester. It says it is style 642. I have given many pictures of this set so please check those out. If you have any questions please ask. I believe this is from around the 1980s.
