LOVE THIS!! I’m a ‘Medium’ in USA. 5’2”, 125lbs, Sz 6 jeans, 34D, w/a minor+ muffin top and a LARGE was perfect! I am really pleased with this very lightweight summer dress!! I would be careful with light colors or in bright sunlight as there’s a slight chance of silhouette see-through..but nothing some under-spandex shorts won’t fix if worse comes 2worst. It’s actually really cute and looks good as a (1pc!) outfit with no effort...so I will probably get another [pink?] in addition to the navy. Lately, everything [tank tops] I order has arm holes that are way too revealing- but these are a really good fit. I don’t typically care for tops w/the awkward long ‘strings’ that serve no purpose 🤨- but these don’t look terrible even though they are extremely long. I folded each in HALF- then did a tight loop chain down it & ended it with the tassel through the end- I think it looks good- like it’s meant2be & it won’t be in the way. Can make chain tighter/looser to adjust length, or cut off!
