And the 26-year-old knows when she is on to a good thing, buying up different versions of the same dress.
Amelle stepped out in the same £69 polka dot dress in different colours over summer. The pop starlet wore a blue version of the Vivien of Holloway frock for a night out at a Soho private members club this week with boyfriend Tom Benn.
Recycled goods: Amelle updated her dress by adding a belt, stockings and black heels. The singer went for a more colourful look in June with red snakeskin heels
She also rocked a red version to party with fellow girl band members Vanessa White and Rochelle Wiseman of The Saturdays at an F1 party at Centrepoint in July.
The 1950s-style 'Halterneck Pencil Dress' certainly looks stunning on her petite figure, so it is understandable why she bought multiples.
The designer's website boasts that there is no need to wear extra ‘shapewear’, such as celebrities' beloved Spanx, beneath the dress, as it boasts a 'boned and lined bodice that lifts the bust into a subtle bullet, and gently nips the waist for a torso that would make Jayne Mansfield envious.'
But Amelle needn't worry about 'nipping in' her washboard stomach. She often flaunts her abdomen in cropped T-shirts, and with a figure like hers, who can blame her.

Reports this week claim that following her split from ex-boyfriend Freddie Fuller in March last year, the Sugababe was so heartbroken she shed two stone.
But her toned body is more likely the result of hard work. The singer revealed recently that she is a fan of Bikram yoga, a style which sees devotees exercise in a specially heated room to raise body temperature and allow deeper stretching of the muscles.
She told Closer magazine recently: 'Bikram yoga is yoga but in a heated room like a sauna. You sweat like mad and toxins pour out of you.
'I swear by it and I think I'm looking pretty good!'

Amelle also works out with a personal trainer, and has been keeping followers on Twitter updated with her strict regimen:
'Morning every1!! About 2 start training! A little early 2 waiting in my car with a coffee. Xxx' she tweeted this morning.
Her trainer clearly demands much from the singer, who was early to bed the night before.
'Off 2 bed now,' she tweeted on Thursday evening. 'Had a great night. I've got 2 see my PT 2morrow at 6am again! Night night every1.xxxx'
'Went 4 a 4 mile run 2day!! Just getting my hair done now, then going 4 dinner later. Hope every1 is having a gd day.xxx'
