Perhaps you should wear tops with waist belts, this accentuates the waistline thus giving a better shape to the body. Also, consider tops with ruffles or detailing at the shoulders to give the illusion of broader shoulders.
You can also consider tops with slight gathers at the bust area to give the illusion of bigger shaplier bust. Avoid tops that has totally no allowances at the bust area. It will only press the chest flatter.

As for jeans, try to find low waisted ones that sits on the hip. This would give better curvature to the buttocks area.
Hope these helps.

Wow....which image consulting firm is free?

There's always push up bras to help. Not heavily padded ones but enough to create the sillhoutte of a cleavage. As for the butt, try to look for uplift jeans. But its kinda hard to look for that in Malaysia
