Labor & delivery

DS
Has anyone (or do you know if you can) worn something other than the hospital issued gowns for your labor? I've seen on Pinterest some comfy looking robes or "Jammie" sets and I just feel like I'd be so much more comfortable in one of those. I've always hated wearing hospital gowns. I asked my mom (granted she hasn't had a kid in 15 years) and she said they won't let you because they need to be able to access you for ivs and such. Which I'm pretty sure they can still do with your own robe on? Just curious if anyone's worn their own stuff for labor.  
 
I attached an example of what I'm talking about :)
