Yellow and purple floral Gunne sax

Size 9 Excellent condition. I haven’t seen any flaws. It is 50 years old and there may be things I miss. I would like to find it in a size 11 as it’s tight on my shoulders. It fits me with my measurements 36-26-38 I accidentally ripped the dress on the bottom tier of the skirt. A dart could be placed to repair it. Bust-16.5” Waist- 13.5” I have pictures of measurements if needed. 💛💜
