This passes the etiquette for a formal day occasion—better if you tailor it.
Size: Small, Color: Grey
Speaking to Americans here. Size S fits a perfect "walmart small". (tall) But the waist of the jacket is boxy. If you went to a tailor, and had the waist fitted for 80 freedom-eagles, you'd still come out ahead. This is great quality for three-piece suit. I'm skipping the vest, as it has no special features that pair it with morning suit. It's just a cheap, shiny prom-rental vest. Trouser waist is a perfect fit. Fabric feels genuine for a lightweight summer suit. Contrary to some of the illustrations, the trousers fit on the "natural waist', not the "blue jeans waist". This means you need to pull them up, like formal wear of the 20th century, so the ankles don't puddle. Wear the trousers with suspenders. The hem of the trousers is funky. But traditionally, you have that finished by a tailor as well.

Good suit and worth every penny
Size: X-Large, Color: Grey
For the price it's Pretty good and Nice quality. Normally one of this Quality if $300 and up. Only thing is, if your a Xl but not slim you may need a larger size. But if your Medium to slim it's a good fitting suit
