The tweed word does not make this wool
I would let the black-and-white blazer be decorative, not misleading.

I read the fibre line before I read the mood. The First Love Lurex Mixed Tweed One Button Blazer has a name that could send someone looking for wool, but the listed composition is 100% polyester. I would consider it as that garment: a decorative black-and-white blazer. I would not sell myself an imaginary heritage jacket and then blame the real one for arriving.
The supplied live listing offers 2XL and 3XL in Black/White, with both variants available. Those are the choices, not the start of a size range I can helpfully invent. Lurex and mixed tweed appear in the title; I have no separate fibre breakdown for either term. The composition line is the only percentage statement I would repeat. I cannot tell you the fabric's feel, weight or scratchiness from that information.
I would first style it with a black crew-neck top, straight black trousers and plain loafers. This would make the jacket the change in an otherwise quiet outfit. No coordinating metallic bag would be required. I like a decorative piece better when the rest of the clothes are allowed to remain employed rather than become supporting scenery.
For dinner, my second suggestion would be a plain navy dress and dark ankle boots, with the blazer worn open if the fit permits. I would keep jewellery small and let the black-and-white pattern sit against one continuous colour. That is a proposed combination, not a report that I have worn this jacket over a particular dress. Sleeve room still has to be checked.
A third approach would be a white shirt, dark straight jeans and low black shoes. I would leave the shirt collar uncomplicated and avoid adding a patterned scarf. The contrast between ordinary denim and a more decorative jacket is enough of an idea. If an outfit needs an explanation of the concept, I generally remove something before writing one.
The one-button description makes the fastening an important arrival check. I would look for pulling around the button when fastened, then compare the hang when open. I would also inspect the shoulder position, sleeve reach and the way the lapels lie. I cannot infer any of those fits from 2XL or 3XL. I would ask for garment measurements before ordering if the shoulders or upper arms are usually difficult to fit.
There are no care instructions or garment measurements in the supplied listing. I would read the actual care label before cleaning and would not promise that polyester makes this machine washable. Construction and trim matter too, and they are not fully specified here. On arrival I would inspect the inside seams and fastening attachment without claiming a particular lining or pocket arrangement exists. A long product name is not an inspection report.
Skip it if you want wool tweed, a subdued surface without decorative interest, or a confirmed low-maintenance cleaning routine before you order. I would also pass if neither available size is a sensible starting point. Tidilo is our sister shop. My verdict is a conditional yes for a reader who wants this specific polyester blazer and can check the fit, not a claim of independent testing. The honest description is shorter than the fantasy and considerably more helpful.
