With the final only one day a way, we've already taken a look at the top five X Factor style looks this series and unsurprisingly this lady came out on top.
Could this show have not only unearthed a new singing sensation, but a new style icon in the making too? We only ask because Alexandra has had an amazing wardrobe this year for her live performances and has always looked stunning.
Our only criticism of the lovely Alex was her crazy jumpsuit creation and beehived hair-do she wore last week; fingers crossed that doesn't make a reappearance in the final.
Alex has also managed to drop four dress sizes during the competition, meaning she can carry off her some gorgeous outfits with new figure-hugging curves.
Maybe she's been taking some style tips from her mentor and fellow fashion icon, Cheryl Cole. Whilst Diana's look has been praised as quirky and cool, It's Alex who has had the show-stopping gowns, tight PVC leggings and a range of body-con colourful dresses.
We have a look back at Alexandra's on-trend looks from this series...
One Shoulder Wonder
Oh Alex, you've excelled yourself with this dress. One shoulder designs and sequins are huge news right now and they will carry through to next season too.
Body Con Beauty
Loving the colour combination and the body con look of the dress. This type of bandage style is huge with celebs right now, but true to form Alex goes for a high-street copy from Reiss. We approve.
PVC Queen
Mrs Cole donned some similar leggings in week one of the live shows, and clearly she's passed on some fashion knowledge to the lovely Alexandra.
