I don't how much barber and tailor cost in the US, but that can be a substantial amount like 20+$ for a barber and a few hundreds for a suit. That's, a whole lot. (SG/JP)
For tailoring, it's a pretty rarely needed service that's impossible to do yourself, but it pays dividends for years.
It sounds stupidly simple, but if your clothes don't fit you, don't wear them.
