I was going to put up something about this after I delivered my baby, but since someone asked… Anyway, I’ve been there twice already.
First, congratulations on the baby. Focus on your health and your baby’s health, and things will get a tiny bit easier.
Second, in terms of fashion…
1) Don’t expect to get your figure back for at least a few weeks, if not longer. You may have eaten perfectly and exercised, but you’ll still have some extra weight and extra skin left. Don’t go crazy over it. Wear your slightly oversized clothes that you wore in the first trimester. And for the first week or so, focus on comfort and don’t worry about looking fabulous.
2) After the first week or so, once you’ve gotten some kind of routine going, do start working some fashion and beauty into your routine. Take a few minutes to wash your face and apply moisturizer. And do get dressed each day, even if you have to wear the oversized first trimester clothes.
3) Surplice/mock wrap tops are some of the best tops for new mommies. They’re less cumbersome than real wrap tops, so they accommodate breastfeeding better, but they also flatter your large breasts while camouflaging the residual tummy bulge. Fitted stretch button-down shirts are also some of the best, simply because they’re so easy.
4) Get fitted for a new bra ASAP. You’ll need it.
I hope this helps.
