Lingerie or Diaper?

About to go to the store real quick…am considering stopping at the local sex store/gloryholes place(it’s a huge maze of dark corridors and small booths with porn on. Always quite a few guys standing around waiting for fresh meat. But no, chances are nobody’s got a big dick there)
Should I wear lingerie or a diaper under my way too tight embarrassing clothing??

Deciding between white lingerie and black; will try to include photos of me in each Can’t find pics of the black one but it’s same
