Did anyone else see the nip slip?

Did anyone else notice that she had a "wardrobe malfunction", when her nipple slipped just over the top of her gown? It's right after the part where he throws her in the lake & she pulls him in w/her... They're laying on the dock in their underwear chatting & whenever the camera has a close-up of her top half, u can c the top of her left nip, lol!
