Quality Casual Suits for Men at Affordable Prices  

Men’s casual suits are an ideal choice for gentlemen who want to look stylish without compromising on comfort. Casual suits offer men a relaxed appearance that is best suited for casual and smart-casual settings. Most casual suits can be dressed up or down, depending on the event’s formality, making them a versatile wardrobe essential. 

There are certain fabrics that make a suit a less formal choice than another, such as cotton and linen. Linen in its natural state is a very wrinkly fabric (which is also part of its charm). Cotton, while perfect for warm days for its breathability, is also considered a slightly casual choice for a suit, as it doesn't hold its shape well throughout wear.

Modern casual suits feature new elements – other than the fabric or fit – that make them perfect for laid-back occasions. For instance, relaxed tailoring combined with patch pockets creates a casual vibe that is perfect for weekend getaways, Sunday brunch with friends, and anything in between. 

How to Choose the Right Men Casual Suit

Start off by selecting the fabric. It’s best to prioritise comfortable fabrics either cotton or linen blends, and opt for less formal colours such as beige, light grey, and green. The fit of the suit also matters, something unstructured like a relaxed-fit suit paired with sneakers creates a laid-back look. 

What relaxed construction looks like:

• Unstructured shoulders: Avoid heavy shoulder padding for a more natural, relaxed silhouette.
• Patch pockets: These external, stitched-on pockets are a casual detail often found on casual blazers.
• Minimal lining: Many casual jackets are unlined or only partially lined, which makes them lighter and allows them to drape more naturally.
• Soft canvas: Less internal structure means a softer, more relaxed drape and greater comfort.

What a comfortable fit looks like:

• Jacket: The jacket should fit properly in the shoulders but with slightly less waist suppression than a formal suit. The sleeve length should show a quarter to a half-inch of your shirt cuff.
• Trousers: Trousers can have a slightly tapered leg with a "no break" or "slight break" hem for a modern touch. 

Accessorise for the occasion by selecting the right pairings to achieve a casual look as follows:

• Men Shirts: For the most casual vibe, wear a simple, high-quality crewneck T-shirt. For a slightly smarter approach, pair it with a soft knit polo or a casual button-down shirt.
• Men Footwear: White leather sneakers are a staple for modern casual suiting. You can also opt for loafers, suede chukka boots, or Chelsea boots. Avoid formal dress shoes.
• Men Accessories: Minimalist accessories will keep your look clean. Consider a casual leather belt, a watch with a simple strap, and a pocket square in a casual fabric like cotton or linen.
