When it comes to outfits, singer Lady Gaga puts no shame on clothes, especially with her ongoing world tour to promote her album "Born This Way".

Now that Lady Gaga is preparing for her much-awaited Sydney Monster Ball happening tonight, now is the perfect opportunity to look back on some of her outrageous outfits for the past weeks. From rayon to leather, the singer has used all possible kinds of fabrics to make her outfits more dramatic. Famous for using feathers, spikes, and neon colors, Gaga incorporates all these little details to make her look unique. In Taiwan, the singer dressed like the queen of hearts in a press conference and looking like a harlequin on another.

From her aquamarine bob to a completely different hue of platinum blonde, Gaga emphasizes her radical looks with her hair to keep the "weirdness" factor consistent. After winning the CFDA Fashion Icon of the Year award, the singer added length to her light blue bob and even adding soft curls later on. When it comes to make-up, Lady Gaga makes sure she's always ahead of the game. During a press conference in Tokyo, Japan, the singer removed her glasses, closed her eyes, and revealed a mask-like doll eye make-up. It makes the singer look like a pop up doll fresh from the isles of any Japanese toy store.

No one could guess what the pop star will be wearing during her concert tonight, but whatever Lady Gaga chooses to wear, she'll still remain one of the world's most celebrated and opinionated fashion icons.
