brings me to today’s formal fashion
Color: Brown, Size: X-Large
the peak lapel made me feel sharp for the big family dinner. the slim fit worried me, but it was surprisingly comfy, not too tight on my retired belly. the pockets are deep, which is great for my reading glasses case. didn't need much ironing, just hung it up. a solid, non-fussy suit for us old guys.

Works for Dress-Up, Not for Formal Events
Color: Brown, Size: Medium, Color: Brown, Size: Medium
This brown tuxedo is about what you’d expect for under $100 on Amazon. The fabric has a pretty brocade pattern but it’s very thin and floppy. The jacket is lined, which helps give it some structure and makes it look a lot nicer, but the pants don’t lay well since they’re unlined and lack structure. The brown color is actually really nice—rich without looking too chocolately, almost leaning burgundy. That said, the fit on both the jacket and pants is surprisingly good. Overall, this is a fun tux for a costume party or one-off dress-up event, but not something you’d want to rely on for a wedding or a truly formal occasion. Just keep your expectations aligned with the price.

A true beauty
Color: Red, Size: Large
This tuxedo set is so beautiful. The red is extremely striking and is sure to grab everyone's attention. I ordered a size L, as I am on the cusp of Medium and Large. The pants fit very well, and they have some adjustment points around the waist in case they need to be let out a little more. Also, in the waist band is some elastic portions, which make finding the perfect fit something you won't have to think much about.--- they will stretch with you. The jacket feels like it is custom fitted by a tailor. The quality of this tuxedo, considering the price point, is exceptional.
