HIGH heels may work for some women, but Stefanie Sun isn't one of them.

The local songbird held her The Answer Is... Stefanie Sun World Tour 2009 at the Indoor Stadium on Saturday night.

And what marred an otherwise brilliant performance from the 31-year-old - who just returned to showbiz after a two-year hiatus - were her awkward moments in her stilettos.

Stefanie appeared during the opening song in a sequin-adorned gladiator costume with matching gold high-heeled boots.

A mock fight sequence followed where she wowed the 7,500-strong crowd with the visually spectacular performance.

Stefanie excelled with her nifty dance moves while rooted to the ground but the times when she tried to work the stage, her discomfort showed.

Bobbing slightly awkwardly to the music, her restricted mobility caused her to take small, hesitant steps which contrasted greatly with her beautiful, larger-than-life vocals.

Her second outfit change didn't help either.

Although Stefanie looked ravishing in a pouffy dress and swept-up ponytail, she was once again in extremely high-heeled footwear - this time, mules.

This sweet get-up was perfect on the singer, famous for her girl-next-door image, save for the fact that she could hardly move.

Her exit from this segment of the show even led her adoring fans to take a sharp intake of breath.

Why?

Stefanie wobbled up two flights of an ascending platform and, for a moment, the petite songstress looked like she was going to fall.

With the entire stadium watching, she completed her shaky ascent, much to the relief of the full capacity crowd.

The show begins

But it wasn't all nightmare on heels for the pop sensation.

Midway through the concert, Stefanie took to the stage in a black grunge outfit with purple socks and low-heeled Mary Jane shoes to match.

Her less formidable footwear made all the difference.

On a night filled with a futuristic-themed stage and costumes, this was when the show really started.

Grooving to the up-tempo The First Day, Stefanie's sexy, high-energy dance moves got the majority of the crowd on their feet.

From one side of the stage to the other, Stefanie belted out the hit while dancing with unabandoned passion.

And the excitement and infectious energy that swept the arena was pure magic.

Stefanie, who looked like she was finally enjoying herself, giggled happily as she pranced around and joked with the ecstatic crowd.

And what does love have to do with it?

Everything apparently, as a special someone was seated in the third row.

Stefanie's boyfriend, Dutchman Nadim Van Der Ros, had a dreamy smile as he watched his love give the concert of her life.

The two-year relationship came to light when Stefanie was spotted cheering him on at a triathlon in March.

Said Ms Avaline Wu, a customer relationship manager, 26, who was seated near the Dutchman: 'Stefanie seems different. She's so much more womanly and happy now.

'And it's obvious that he's (Nadim) crazy about her. My friends and I saw him look tenderly at her when Stefanie was singing (the ballad), My Love.'
