Early on, there is no shame in using a hair tie to keep pants that still fit but won’t close the normal way in rotation. Add a longer layer on top with some stretch to cover that awkward top of your jeans zone and you're good to go.
Consider investing in a pair of maternity jeans. Or borrowing a pair. If you really rely on denim as a wardrobe staple, it's not easy to give up and there are some great options out there to last you all 9 months. These are the true mom jeans.
At some point you may not want to wear jeans anymore. You may not like pants at all. Another great option when you get to this point is a pair of pants with an elastic waist. Look for things with some stretch, because the butt and thighs really do as they please during pregnancy, and slim silhouette. Because, fact: slim pants are universally flattering.
One additional option is a bottom-and-top combo aka a jumpsuit. There is really nothing better than waking up, putting on one single piece of clothing that counts as a top and pants all in one and calling it a day. We recommend something in a knit fabric so you can wear it all 9 months, and beyond.
A soft cup bra. Fact: Your boobs may hurt as they grow. The underwire can be a cruel mistress at these times. Get yourself something soft that can accommodate fluctuating breast size and pull aside to double as a nursing bra once the babe comes.
Comfortable briefs. Remember thongs? Many of us might find that thongs just don’t make as much sense when you’re pregnant, for lots of reasons. Do yourself a favor and get some comf undies that fit. Even better if they're seamless so you can wear them with all your body-con maternity pieces. You may need to think about sizing up as you get on in trimesters.
Socks. You may be getting up in the middle of the night to pee quite a lot. Cozy socks can help ease you in and out of bed and minimize the bracing effect of cold bathroom floors. This is a small but high-impact luxury that you’ll appreciate when you’re on your eighth nightly round trip.
