1920's Peak Lapel Jacket and Waistcoat

[GoldenEraFan]

It's my size and a bargain price to me, but I can't tell if it's a tuxedo or not.

I think it is a tux.

I think it is a tux.

Yup.

It's 1920s, in your size for $25: buy it!
Even if you don't think you need a tux at the moment, in the future, you'll be invited to some event and need a tux, and you'll think 'Why didn't I buy that $25 1920s tux?'
In my experience, unlike most other suits, finding trousers to match a dinner jacket is possible (unlike trying to match trousers to an orphanes suit jacket). Also, the most likely locations for wearing it will be in a room where the lighting will make it easy for slight differences in shade will pass unnoticed.

au contraire. In dim lighting, subtle differences in shades of black are the most easy to spot!

This is because the rods are much more sensitive to light than the cones (though insensitive to colour), and whose only job is to detect contrast. This is why we see mostly in black and white in the absence of artificial lighting.

Foiled by science! I still maintain it is easier to find a close enough match. I can't see the difference on mine (which are mismatched) and if I can't spot it, I'm not concerned. Of course, if the jacket is faded, finding amatch might be a little tricky.

I agree TT. While indeed shades of black can be discernible under artificial light, it is possible to match evening wear.
Easiest with molton/felty black cloth or Barathea. More difficult with worsted. I have a Swedish tuxedo jacket which has almost (say 95%) identical cloth to a pair of German trousers. It is impossible to tell the difference. It becomes difficult to "mix and match", when one is buying online, though. I had the luck of first buying the trousers online, and by chance finding the jacket in a store... I was therefore able to compare them before buying.

The combination I usually wear is a British jacket made in the late 1950s and trousers that I suspect were made in Germany in the 1930s.
