Vintage 70s or 80s Bridal Originals lilac floral lace bridesmaids dress size 10

Vintage 70s or 80s lilac bridesmaids dress with floral lace overlay, size 10. Midi length. In good condition with zipper and all hooks and loops accounted for and fully functional. There is a hook and loop at the top of the back neckline and another on the back where the lining starts. There is one tiny snap at the cuff of each sleeve. There is a small hole in the lace right beneath the neckline on the back right side, as shown. I believe this may have been altered as the seams are raw on the inside (see last photo), so see photos for measurements. ILGWU tag places this between 1974 and 1995. There is no brand tag or materials tag, but the RN number is registered to a brand called Bridal Originals. There is a lighter colored layer of lining beneath the lilac fabric. vintage prom dress, vintage formal dress, wedding guest dress, 80s costume, 80s theme party, purple, lavender, feminine, delicate, dainty, leg of mutton sleeves, true vintage, 80s costume, coquette girl, soft girl aesthetic
