    Good Fit, Fold Lines
    5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.

    Great vest for a great price!
    This vest is more slim fitting, stylish, & flattering than many vests. It fits as expected, but it is adjustable in the back, so you do have some wiggle room to tighten & loosen it if you’re unsure about the size. My son wore this vest to homecoming. He is 5’ 10” & 150 lbs, & the size small was a good fit.

    Great Quality Vest
    Great quality vest versatile for all occasions. I personally felt it ran a bit tight (I ordered a large and felt like I was sucking in a bit the whole time) but I think an XL would have been too big. Overall impressed and happy with purchase.

    BUTTONS LIKE A SMALLER SIZE. GOOD QUALITY.
    DESIGN IS EXCELLENT. QUALITY IS FINE. I WEAR A LARGE, BUT THIS VEST, IN A LARGE, DID NOT ALLOW ME TO BUTTON ... AS IF IT IS A MEDIUM FIT. WILL RETURN, BUT IT IS A VERY GOOD VEST OTHERWISE.
