The PR maven is set to tie the knot with her husband Oliver Curtis for the second time, after he re-proposed following his jail release.
Roxy took to Instagram with a picture of herself in a blush floral applique gown by Oleg Cassini.
"4pm Thursday," she simply captioned the stunning photograph.
The gown, which featured a structured lace bodice, sheer tulle sleeves and a full tulle skirt with a long train, retails for $3049.
The brand also shared a BTS snap from Roxy's fitting, further showing off it's pretty design.
We can't wait to see the gown Roxy decides to wear for her big day!
