The reality star chose a figure-hugging baby blue number with sexy side cutouts to attend the event in London on Saturday night (2 November).
Love the look? Then good news as Abi's dress is called the Jacqui and is available from Es Vouiré and priced at a purse friendly £65.
After the event, Abi simply tweeted: "#teamcurves."
Abi recently told Reveal that it can take her up to two hours getting ready for a big night out. Hey, it's worth it if the results are this good!
"My make-up takes quite a while but I enjoy doing it, so I relax. I put music on, have some wine and really chill and relax," she said.
As for whether she ever has a dress down day, she told us: "When I go to work, I tend not to put any make-up on my eyes and let my eyelashes have a bit of a rest. I mix some fake tan with foundation to give me a glow for the day and then just a bit of lipstick to brighten up my look."
Abi can be seen in TOWIE, which airs Wednesday and Sunday nights on ITV2.
