When it comes to suits - Fitting. Is. Everything.
Details that affect both aesthetic and fit will either make or break your look which is why it is important that every suit wearer pays attention to every element they’re wearing.
There are plenty of reasons why anybody should wear only well-fitted suits, but the most important reason, apart from having a great silhouette, is comfort. A well-fitted suit is comfortable to wear and should be comparable to wearing any other regular clothing.
