This goes without saying but y'all get your clothes tailored. There are so many clothes I've re discovered or had sitting in the back not getting much wear because it didn't fit well or was slightly off. I swear it will turn it into a new article of clothing.
I had my tailor trim a suit he made for me two years ago. It's a nice wool navy suit. It was just roomier than I liked. He trimmed it in the arms, chest, and trimmed fabric under the knee cap all while keeping room in the thigh area and it looks great.
The fact that it is tailored much better to my taste makes me able to wear it with other articles of clothing in my wardrobe.
I'm also getting a sportsjacket of mine let out a bit. Not sure if I gained weight or it was always small.
