Never had to apologize before for quoting Shakespeare and am not about to begin now!
This and many other sage Shakespearean quotes have served me well over the years. Cervantes, too!
Cleanliness, hygiene and courtesy are, of course, extremely important but they go hand-in-hand with dressing well! As a matter of fact, you can't be well dressed and unkempt! No need to try to impress... they just naturally do!
Try it.... you'll like it!
