2. Wear the right bra AFTER pregnancy. If you are nursing, you will probably want to purchase a few nursing bras for easy access. Be prepared for one set of measurements during nursing and a different one after you wean. Your “final” size may not be fully settled until a few months after you wean. Once again, a proper fitting will ensure that you are wearing the right size that offers good support. Sturdy sports bras should always be part of your exercise attire and this is also a great time to experiment with push-up bras and their cleavage-enhancing properties.
