Depending on details, the blazer and jeans may appear either nice or old-fashioned. This combination can be fresh, casual and undaunted with some contemporary options rather than stiff and outdated. Sneak peek at a few tips to wear a blazer and jeans without looking old.
Choose a Modern-Fit Blazer

A contemporary fit ought to be low and lean towards the shoulders, and a little around the waist. This gives it a fresh figure that is up to date. The lighter fabrics and soft construction are also used to ensure that the blazer looks casual rather than formal.
Avoid Dressy Suit Blazers

A jacket taken from a full suit can be too smart to wear with jeans. Rather, choose casual blazers that are made of cotton, linen or textured materials. These are more casual and combine with denim and are not as though a mismatch.
Wear Dark, Clean Jeans

Wear dark or midwash slim or straight fit jeans. No baggy or heavy fading. Clean denim makes the outfit look and stay sharp and modern, yet casual enough to balance the blazer.
Skip the Button-Down Shirt

Frequent and conventional dress shirts may make the outfit seem old-fashioned. Use a plain T-shirt, light knit or a casual shirt instead. These items make the appearance less aggressive and the blazer looks casual and modern.
Pay Attention to Length

An unsuitable blazer can make an outfit old-fashioned. The trendy blaze cut is a little bit shorter. The appropriate length keeps the proportions in check and does not give the impression of an outdated and too formal look.
Choose Casual Shoes

The dress shoes tend to make the outfit tight. Choose clean sneakers, loafers or plain boots. This is because the casual footwear does not attempt to be fancy but instead makes the look simple and contemporary.
Simply and Modern Colours

Neutral colors such as navy, gray, black, or olive are the best. Shine and loud patterns should be avoided. Basic colors assist the outfit in looking fresh and easy to wear rather than old-fashioned.
Desertion the Matching Accessories

Do not be too much of a match with a belt and shoes. That old rule feels outdated. The outfit is comfortable and easy going due to a loose combination of textures and tones.
Wear It With Panache, Not Stiffness

The biggest one is to wear this combo too formally. Make your body pose natural and your hair natural. As soon as the outfit is comfortable, it is automatically more modern and confident.
