Over yer shoulder!

Hello everyone,

First time posting on the forum (yikes!) and I wanted to ask a simple question regarding shoulder drop. How can I accurately measure the drop without the use of a Perkins shoulder device?! I'm usually one for gauging by eye and making adjustments/recutting as I go through fittings but I've recently become obsessed with trying to find a better method... And, I can't find a second hand shoulder device for love nor money, ha ha.

I'm still at the beginning of my bespoke tailoring journey and have slowly been getting to grips with understanding form and fit - more towards ladies suits. However, I'm keen to know if there are any handy secrets to measuring/figuring out shoulder drops and so on before getting stuck into drafting and making.

We all know that Perkins tailoring instruments (and the likes!) haven't always been around, so if anyone can give their advice I would be eternally grateful. :~)

Thank you in advance!!
