Regular clothes after delivery??

This might come off as a silly question but I'm a FTM in the middle of packing for a huge move. I'm due Nov 26. Did y'all fit into your pre pregnancy clothes.. Specifically jeans immediately after giving birth or did you have to wear maternity jeans for a while after? I've only gained about 15 pounds so far if that helps when giving your input/answer. Thanks in advance!! :)
