What to wear to ER?

Carolina • 1 fresh successful cycle 2015 ! 15 month daughter via IVF and going thru FET Aug 2017 🙏🏼🙏🏼 1 embryo ready for transfer!
So please don't get it wrong! Not worried about fashion, concerned with needing something that will make the experience more comfortable. Do u leave ER very bloated that ur normal cloths are uncomfortable? I read someone post that they were relieved to bring socks, etc. for those that have been there, what item did u bring/wear that was a comfort or lifesaver?
