First of all, the jacket, or blazer, is something you can keep wearing from your pre-pregnancy wardrobe. You don’t want to wear it closed anyway, so I am sure you can keep wearing it throughout your whole pregnancy. The trousers are another case though; as you will not ever fit into that amazing pair you got with that jacket (or blazer). From my experience, it is from the moment you find out you are pregnant, that you will also find that your jeans and trousers instantly become to tight on the top. You, nor anyone else, will see your changed body (I am talking about your lower abdomen), but you will feel it! So, the best thing to do is to quickly jump onto the pregnancy-pants-bandwagon, and just go with it. These pants have elastic parts in the waistband, or a complete elastic waistband (whatever you prefer), which you don’t have to show. Which means, no one will tell, and you feel comfortable.
Now back to the suiting-thing. I adore the Emmanuelle Alts from this world who wear ‘suits’ in any way you can think of, every day of the week. Especially ‘suits’ that consist of simple jeans, blazer, a slouchy t-shirt, and some pointy black heels. Good god, this is just one of the most sophisticated looks if you ask me. This can remain your look-du-jour when you are pregnant, just switch the heels for some slip-ons, or something similar, which makes it a little sporty, but without losing its sophistication. You get me, don’t you?
