MISTAKE ONE: SHAPELESS CLOTHING
While a baggy dress or flowing shirt can be tempting, it's usually doing little to flatter your frame.
Instead, women should be focusing on structured garments that show off their figures rather than hiding underneath their clothes.
'A lot of women want to cover those problem areas such as your arms, hips or tummy but by wearing shapeless clothing it makes you look heavier,' Alex explained.
'My advice is to always choose structure over shapeless garments.'
Alex said all women should have a 'well cut fitted jacket' in their wardrobes that has 'some structure and is a little bit shorter and cinches you in at the waist'.
MISTAKE TWO: AN ANKLE-LENGTH HEMLINE
Many women choose to don maxi length pieces in order to hide certain areas of their body.
But this is often doing more harm than good.
'As you get older, you tend to want to hide the saggy knees or you feel a bit more comfortable with a hem down to your ankles,' Alex said.
'This length makes you look a lot frumpier and wider. A good alternative is the midi skirt - it's right on trend at the moment and it stops at the middle of the calf. It's a lot more flattering.'
MISTAKE THREE: TOO MUCH BLACK誤區三：偏愛黑色
While most women love to reach for their beloved black jacket or skinny jeans - it's not always an appropriate choice.
'It's our usual go-to and the reason is that it trims your figure and it's appropriate for almost every occasion,' Alex said.
'But when women are getting older their skin tends to get paler so black can create a harsh contrast which emphasises fine lines and dark shadows under the eye.'
Alex says this can be fixed with a statement necklace to 'bring a bit more light back into the face'.
MISTAKE FOUR: THE WRONG FABRIC誤區四：選錯面料
'As women get older they tend to opt for comfort and will choose something like a Jersey fabric,' Alex said.
'But this fabric isn't the best choice because it tends to cling to those problem areas.'
Instead, Alex advises women to choose clothing in a Ponte fabric or a Merino wool or a Jersey fabric garment that is 'draped or ruched' as it 'tends to graze over your curves'.
