1. Choose stretchy fabric. Buy clothing with a lot of stretch but that fits snuggly around the belly and your curves. Wearing bigger clothes may sound comfortable and practical, but clothes that do not hug your figure will actually make you look bigger than you are and you may be mistaken for overweight rather than pregnant. Choose clothing that emphasizes the parts of your that are not expanding - such as ruched sleeves to show off your arms, cropped pants or skinny jeans if you have trim legs.
