The former 'Harry Potter' star proved she was no wallflower in her mini white gown at the New York premiere for 'The Perks of Being a Wallflower' in September 2012.
We think she probably only narrowly avoided an awkward incident outside Miami's Children's Museum.
Not that we've got anything against see-through outfits; Anne Hathaway looked stunning in a sheer floral number at the 2012 New York City Ballet Gala; we just seriously object to seeing major nippleage in a public place.
I didn't have time to change and then all of a sudden the zip got lower and lower, I rushed on stage and pop! However, even after attempting to wrestle her Favourite Country Artist award from Olivia Munn's hands, the dress never caused any wardrobe disasters.
Aside from past jail sentences and drug problems, Li-Lo is still on informal probation after stealing from a jewellery store in 2011 and, most recently, she was in trouble for lying to the police about a traffic accident and punching a woman who she called a 'gypsy' at a bar.
Why hide her, um, assets? Okay, so we know that this v-neck black number isn't exactly head-turningly daring in the boob department, but we reckon it's probably not appropriate dress for carrying two small children.
