You can wear anything you like to your session. You can wear a bikini or even undergarments. Women can tan nude ( not men) It is whatever your comfort level is. (Please note that if you wear a bra or top any straps will cause a tan line)
Make sure you have the proper clothing to change into after your spray tan session to avoid ruining the application.
Refrain from wearing tight clothes such as yoga pants, jeans, tight shorts, tight tank tops and anything with an elastic waist band. Wear loose, dark clothing instead to avoid messing up the tan.
No heels, slides or strappy sandals or they can leave marks on your feet and cause the tan to rub off. Please bring thin flip flops to your appointment.
If rain please bring an umbrella to avoid messing up your tan.
