Generally, you should buy maternity clothes in your pre-pregnancy size. As maternity clothing provides extra room around the belly and bust, it gives you the comfort you need for your changing body. If you're in between sizes or are still unsure of what size to buy, consult our maternity wear sizing chart. Take measurements around the fullest part of your bust, your hips (under your bump), and your bump circumference, and compare these numbers to the sizing chart to find your ideal fit.
During my first trimester, I thought I might get away with continuing to wear my low-slung hipster jeans for the duration. And I probably could have eeked them out for way longer than I did, had I invested in button extenders or a Bump Bandeau (as recommended by JTryner in an earlier thread). But there was always going to come a point when I got a little larger all over (be it from swelling, fat or, y'know, the extra 2 ½ pints of blood that swishes around in women when they're growing a foetus).
If you are trying to buy on a budget (you have a baby to think about, after all!), Walmart is a great place to look. Its maternity section is brimming with dresses, tops and pants that are both fashion-forward and super affordable. We love Walmart's "Maternity Essentials" section, which has all the basics you'll need for those nine months (and beyond).
I did all of my maternity and nursing gear shopping here and absolutely love it! Thyme Maternity across the street seemed to be the same in quality but has a smaller selection and is a bit more pricey. I have alway gotten great service here and there always seems to be great sales. In the month right after I had my baby my husband went to get me nursing tanks but the sizes he got were too big and when he went back to exchange them he said is was super easy and they were incredibly helpful. I have also gotten nursing shirts as gifts from there and had to exchange sizes and the gals were so nice about it. In some stores you sort of get the eye roll when you have to go return or exchange things or it even feels like the sales people are trying to make it difficult for you, but that has never happened to me here! Great place to shop :)
Horrible experience. Never order online from this company. Actually, never buy anything from this fraudulent company. After they canceled an item, not me, they shipped the rest and only partly refunded the money from the canceled item. After numerous emails back and forth to customer service, they claim it was already discounted. SInce when does a promotion of buy 4 get one free, mean, buy 4 things, and we'll take a little bit off each item, claiming they have all been discounted. To top it off, I even bought 5 things, so even if one was canceled there should have still been the same deal of buy four get one free. I will never purchase anything from this company again, whether online or in store. They cheat customers. They don't even deserve 1 star
