80's comedy Art Model from Ghostbusters?
 

In that terrible movie from the 80s "18 again" there is a quick nude scene? I saw it decades ago, but remembered, perhaps its the blonde actress with a brief part in GhostBusters? She is briefly a nude art model and if i remember correctly, they show full frontal. Of course, if i dont, they dont.

Does anyone know more?

I did this in art college once - nude modelling.
I'm male of course, and as a student I needed to earn a little extra money so I did what was necessary.
I modelled for an adult drawing class in the evenings, mainly amateur artists of fifty years plus, male and female. But the first time was the hardest and I really found it difficult to control my dick in the presence of women, even though they were much older. AND there was one male in particular who was openly gay and who kept on making comments about "getting to know you better" and "upstanding member of the modelling profession" etc.
Modelling cures you of any self-consciousness!
Footnote. This is actually how I met my first wife. She turned up for an evening class and we got talking afterwards.

Life Models
 

My wife has been "Life Modelling" for artists on a part time basis since the mid eighties when she was introduced to a master artist and he asked her if she would sit a portrait session at his studio, after a few session at his studio he asked if she would pose nude and this led to her being asked by other artists to pose nude for them.
Good life models are hard to come by as holding a pose and knowing how to pose to the best effect takes a great deal of dedication and is often physically very demanding.
Although now turned 60 years of age my wife continues to be popular with artists as a life model and poses for private sessions and also art classes, during lock down she was posed for regular life drawing sessions via zoom.
