Furthermore, you can't dress too casually. For example, wearing slippers and a vest with two ribs will be worse, and people will feel less formal. But in this case, it is the groom who is the protagonist. Don't dress up too presumptuously. In the choice of color, I think everyone can choose to wear some brightly colored clothes, which stand out. And in the choice of materials, I think we can choose leisure suit or other styles. Anyway, leisure is very good, so we must ensure that the style is generous and comfortable to wear.
Also, I think 20 years old is still relatively young, and I can't wear too exaggerated and too social, just shirts and slacks. Also, I think the understanding of exaggeration is different. What I think is exaggerated are tights and bean shoes, as well as backless clothes that young people prefer. I think if you dress like this at the wedding, there will definitely be many elders who think these children may be a little strange. There is no way to express this standard in a specific word. I think so, not too? Spirit boy? .
Actually, I think it's best not to wear black. I just thought it was nothing before, but now I think today is your brother's big day, even if it's to be cool, don't dress like this, because there are more than one chance to be cool, but if you dress like this in black, it may be seen by your elders and affect your brother's mood. So pay attention.
