In fact, giving a four-piece suit is also part of the dowry, so I feel that there is nothing special to give except a four-piece suit! Actually, there is no other meaning.
To tell the truth, if the quality of the 4-piece set is not very good and the price is not very high, the gift money sent between girlfriends is definitely out of reach! So it is also a way to save money.
Actually, to put it bluntly? It's just a wedding present. There is nothing symbolic. I know you just want to give some auspicious wishes while giving gifts.
