Topshop floral sleeveless dress Size 8. Lined

Topshop floral sleeveless dress Size 8. Lined, flowy, longer in back than front. Measures 33.5" in front and 47" in back. 36” bust, 26” waist which is elastic so can stretch a lot. Last two pictures show a very faint mark on the front. Looks like a light pen mark. I hadn’t noticed it at first.
