You could not possibly lift your regular old top up when you had to breastfeed your baby. However, for the new mother, you do not wish to have half your tummy hanging out for the world to see when you nourish your child. You may not wish to stretch your cute top that still fits ad flatters you comprehensively.
Your best bet would be to look for maternity shops Singapore offering designer apparels for pregnant or nursing mothers. They would provide you with an array of designs and trendy clothes that makes it easier for you to nurse your baby without being uncomfortable.
