What underwear do you have on at the same times? What is the. material, also what is 'in' the suit? If it's a mix there may be enough non natural fibres which make it sparky.
I carry a lot of static, so much that I cannot wear a wrist watch as they simply stop! Years ago DH and I couldn't kiss due to the 'modern' fibres

which were quite painful on pulling apart

I never use conditioner now. If a machine has a good rinse cycle, any smell etc. will disappear. So much for the advert which states that the conditioner perfume remains ..... yep, if the item isn't worn/washed ;-)
I will be interested in finding out any solutions. Operating theatres have a mat outside to draw static .........
