The last time you posed in your skivvies you ended up in the pokey.

Next time keep your thrills under wraps with pinup pro Bombshell Betty.

The queen of Bay Area burlesque recently launched her Pinup Workshop Tour in L.A. and stops here this Sunday. Held in the newly renovated King Suite of Union Square’s Hotel Frank, the six-hour shoot welcomes Vargas vixens of all curves and cultures.

Bring your naughty knickers and let Betty’s team do the rest. They’ll set you up with a retro hairstyle, makeover, and props, then pamper you and the other poster girls before you pose for more than 200 sassy (but classy) photos.

Not a joiner? Choose another day, time, and location for a private session. It’s pricier but worth it.

And definitely beats parole play.

Pinup Workshop, Sunday, 3-9 p.m., at Hotel Frank, 386 Geary Street, between Mason and Powell Streets (415-986-2000 or hotelfranksf.com). For more information, go to bombshellbetty.net.
