Perfect for Prom, the satin detail elevates the look
Size: Medium, Color: Black, Size: Medium, Color: Black
This sport jacket was a great item for prom. We had it altered and taken in a little to be more form fitting. It was lightweight enough to be comfortable and the color was a nice black with satin collar. It was a great value for the money and this is the second one I've bought. The first one was red for freshman homecoming. Fits true to size as this is a medium but we did want it a little more form-fitting.

well made
Size: Medium, Color: Black
My son looked SO handsome for Prom. This suit was surprisingly well-made for the cost. After pricing tux rental, this was a no-brainer.

Much better quality than I expected
Size: X-Large, Color: Black
Better than I expected, actually a quality jacket. I'd wear it every day. The fit is perfect and exactly my style. I can't say much about washabiity due to having mine drycleaned
