In recent years, men have become more and more fond of suits. As a must-have for men's formal wear, suits can give a man elegance and taste through a variety of custom designs and word combinations. So, can suit be paired with these accessories?
Tie
According to common sense, collar area is where seasoning tastes best, and it's also place that can have most changes. For newcomer Xiaobai who has just entered pit of suits: it is recommended that ties be polka dot, geometric, striped or sheer, and width should be more than 7.5cm to match with formal shirts and suits. It is versatile and suitable for any occasion. 
Pocket square
I don't know what to choose for pocket square. I advise you to choose a solid color or pure linen white. The standard is taken as basis, and it is convenient to make changes in future. As for how to play pocket square, if tie is tied with a four-hand knot, it is recommended to fold the pocket square in a straight line, which is simple and easy to learn.
Belt or belts
From point of view of use, these are just accessories for fixing trousers. If you want to dress more formally and tastefully, suspenders are recommended. Compared to a simple belt, men's suspenders look more elegant when worn and can better support trouser line. As for whether you want to use a clip type or a button type, you can judge by what you wear. Of course, there are also dual-use multifunctional belts that support button type and can be fastened directly.
Portfolio
No matter what kind of work you do, it's okay to bring briefing notes, written papers, pens, etc. A well-fitting suit that can be worn with a clutch, briefcase or large bag. If there are not many documents or non-office needs, a clutch is most recommended stylish choice.
Shoes or socks
The most important thing in shoes is color matching. Pair textured leather shoes with a matching suit, try to keep things simple, and opt for suede shoes if you want to wear something casual. For socks, try to match color of pants or shoes alone (e.g. gray pants with gray socks, black shoes with black socks) to avoid visual truncation.
When we really find our own style of wearing a suit, we can improve our personal temperament and show our personal charm.
