Acceptable. But you would have to be willing to let them send the Tux to you. WhY? Cuz you would have enough time for two fittings. I.e. Measure on your first trip. Fit on the second trip morning then in the evening of that same day after your pantip expedition. Then allow them to send it to you to your home.

Or, if you're lucky, one/two fitting sessions is enough and they measured and made your suit correctly then you can take it home right away.
