As we are talking about basic stitch work, a good skill for sure, but I admit I'm pretty snobby with my dress clothes. Find quality used stuff and have it cut. And or, get cheaper clothes and talior em to you.
A nice button down from Ross maybe 20 bucks + 10 trimmed to your body way less than off shelf polo with a bare med cut.
I have some suits passed down to me when I was a teen and I'm closer to 40 than I like. They were well cared for and I didn't need to buy suits but 50 bucks getting fit to me, I still look fly in them.
Also this came up in a funny story and I'm sure it's stupid simple, but grubhub etc is absurd don't use it. Even if you have a dodge viper or some race car, your 7 mpg to the pizza shop and back is cheaper than delivery fees. I'm truly baffled how those places caught on or last.
