Hoarding clothes:
Most people get comfortable in one particular style, says Constantine, adding: "The clothes that you always wear are probably safe and repetitive."
Her advice is to put your trust in a good friend who'll be honest and objective with you and critically evaluate your closet.
"The stuff you never wear is probably because you're scared of it, or it's expensive or you bought it on sale. Maybe it doesn't fit well, then you're hoping when you lose weight it will," she said.
"Put all your clothes into three piles - clothes you never really wear, clothes you wear sometimes and clothes you always wear," she added, and get rid of what you don't need in there.
