Where Do Smaller Gentlemen get a Suit!?

Hello everyone!

I’m badly in need of a nicely-fitting suit (tight-ish around the waist and not too big on the shoulders) but I can’t seem to find anyone who can do it!

For context, I am 5’7” (170cm) and 105lbs (47kg). I already tried a formalwear place near me and they said they couldn’t help and asked me to leave.
