Renting tuxedos is one kind of an emergency case idea or an alternate condition that we take in our hands when we don't have enough time or money to get a good looking posh tuxedo from a retail shop or get it stitched from a leading tailor who is skilled in suits and tuxedos. Renting might be a good option for people who want a tuxedo for a day or if they are wearing it for the first time. If you already have a tuxedo with you, you might be trying to wear that same thing again than buying a new one for extra cost or renting one as a cheaper option.
Anything that you plan to do as a short term relief has to be strong enough and worthy to handle the situation so renting should not be an extra stress on your head and should only ease the situation. Apart from the fact that rental tuxedos need a lot of adjustments to be done if it has to fit you, sometimes it will be hard for you to hide that it is a rental tux. People who wear tux regularly or who knows better about this kind of clothing will easily identify the difference between a rental tux and the one that is yours.
Rental tuxes don't have sleeve buttons and this is one among the most obvious things that make it stand separate as a borrowed one. The reason for which a rental tux being without the sleeve button is it is a practical difficulty when you need the sleeves to be adjusted according to the size of the different people who rent it. The tailor cannot be removing and fixing the sleeve buttons all the time he makes an alteration. Though renting is an open choice that is economical in most cases, it is hardly a comfortable choice to carry out.
