I did it that way, when I {ugh} needed a uniform for certain occasions. You would be an unusual US male if.. you had the foggiest idea of the nuances of style, cut and esp - what tailoring by an expert - can do for that "first 10 second impression". And these all are a bit different details for different body shapes, too!
Be assured that, whatever you notice in the mirror shall be quite less than - especially! what will be er 'deconstructed'? by an office of mostly females (who likely pick out their SO's stuff too).
Also.. right now there are sales. As when I shopped. I ended up with a much more expensive (priced) suit than I imagined I 'needed' - for not much more than I hoped to pay. Consider the time spent for a final fitting - amortized over several years.
(Yeah it's weird - but we're tribal and run in packs - remember?)
Enjoy this adventure in a surreal environment --

PS - that "second pair of pants" may not be a bad idea either, if you'll be living in this on-site, daily (?)
