Worked for me.

Also dressed me for the OTHER big day: had to decline the cane and hat even though they said I needed to (I quote) "go out like a player".

Tell 'em you want to dress like a banker. Or a bank teller., with aspirations.

(Saville Row is also nice, but rather pricey, and you'll have to stay in fighting trim for the rest of your days to justify the expense of fitting in the the thing. Not necessarily a negative).

First impression is made in about 5 seconds and will seal the deal: everything else is lipstick. No guarantees, but looking sharp, and feeling sharp, doesn't hurt your poise and confidence.
