Hello and thanks for your interest. I was a professional entertainer for 30 ish years which included being the youngest toastmaster in Great Britain for a while! 
I wore as an alternitive to my Toastmaster jacket after a formal wedding breakfast it is very smart sparkly but not glitzy main jacket black with silver

Please do not compare this to the very thin cheaper options.
when this fitted me perfectly 

I am 5.10 
collar 16
chest 42 ish 
waist 38-40 
I would describe this as large possibly XL
I have not toastmastered for 10 years so its been in a wardrobe in a suit carrier in a smokeless dog less home 
The Shirt bowtie  & trousers are NOT included 

Top of shoulder to cuff 67 cm inside arm to inner arm to jacket 47 cm


I have also the pair of tailor made heavy (possibly Woollen) trousers that I bought at the same time if anyone wants at additional charge. 38-42 waist (short) 

We are in Essex so if you want to try on no problem

25 years ago this cost me approx £400 so I suggest now would be £600-£800 new

When photographed to put this on sale I have put on a lot of weight so it looks  a bit small on me!!
