You can create curves by specifically combining voluminous and figure-hugging fashion. For example, try pairing an oversized top with skinny jeans or a tunic with overcut shoulders with trendy jeggings.
Of course, this style works the other way round, too: a tight glitter shirt paired with paperbag pants looks wonderfully feminine! But make sure you tuck the shirt into the waistband. A flared maxi skirt also creates volume on your lower body and goes great with a figure-hugging top.
But beware: never combine volume with volume!
