  • Should I even buy newborn clothes?
    If budget is a concern, you can buy secondhand clothes. ThredUp is a good place to look if you need or want to shop online. Source: almost 3 years ago
  • Where should i buy work week & recruitment outfits?

  • Fashion mamas - need your wisdom! Favorite pants??
    It sounds like you've gotten a lot of good suggestions on brands and styles, but one way to make it more sustainable is to buy things secondhand. I got a lot of my maternity clothes from ThredUp and had a good experience so that might be a good resource if you're willing to shop online and already know what you're looking for.

  • Weekend Promo replaced with a worse one?
    With enough searching, I can even get to a thredup splash page for the 60% off sale, but that code doesn't work. It legitimately displays on the thredup.com website, but only from a search engine. Go back to the home page yourself and it'll be the lesser promo, Star. Source: over 3 years ago
  • SHEIN Maternity clothes
    I got most of my maternity clothes from ThredUp and it might be a great option for you. It's secondhand clothes, so it doesn't have the same ethical or environmental issues as companies like Shein but is way more affordable than a lot of other options. Source: over 3 years ago
