Lindsey Vonn found herself on the thong side of fashion at the ESPYS on Wednesday ... when a gust of wind caused her to suffer a wardrobe malfunction right on the award show's red carpet.
Vonn rocked a purple, strapless dress for ESPN's annual bash in Hollywood ... and while she looked amazing -- a strong breeze ended up exposing a bit more of her bod than she had intended.
Her underwear was out in full view of photogs as her thigh-high split blew apart -- but fortunately for the skiing legend, someone raced in to help her cover up until the wind died down.
