how can I solve this problem?

Hello guys!

I tried to set-up my unisex online shop but I got a problem…

for example;
Let’s say I have 100 unisex shirts in stock and I want them to be listed in two different sections:
first section: women -> shirts
secound section: men -> shirts
(in 4 different sizes)

In the womens section the shirts are worn by female models and the men sections by male models. (but it’s exacly the same shirt)

my question is:
How can I bind these to one stock?
(so no matter from which section the shirt gets bought the stock needs to change)

And my possible soulution would be:
can’t I just create one product and add to both sections and just safe the images of it per section?

I hope you get my case and can help me to solve it…
Any help would be much appreciated!
