Hey when I had my op nearly 2 weeks ago I took with me button up pjs, slippers, dressing gown, toothbrush, charger, magazines and a pillow and some biscuits in the car. I was a day case but they say prepare to be staying over just incase. I travelled in leggings and a shirt but ended up just wearing my pjs home! All you really need post op is dry shampoo, anti-bacterial wipes, sports bras, and my v pillow has been a big help. You have to wash with only antibacterial soap on the morning of your op I bought a bar of soap by detol for sensitive skin. You have to take all piercings out including belly bars. I recommend the Macom bra and the George asda sports bras which you get 2 in a pack for £7. Hope this helps good luck xx
