For the benefit of a few of you let me spell out a certain word: H-Y-P-E-R-B-O-L-E.
People can have different opinions on what looks good (e.g. black suit vs. navy suit; narrow stripe vs. wider stripe; darker shade of blue vs. lighter shade of blue; etc.), but labeling something as "fashionable" is a waste of (my) time. If people want to wear something because it has been dubbed as fashionable by some designer who wants to stand out and start a trend that is their choice. However, when something looks ridiculous I don't care what other label it is given, it still looks ridiculous. Fashionable, but ridiculous. Wearing triple layers of sleeves, each layer ending higher up the arm than the one beneath it such that the jacket sleeve is 4-5 inches from the wrist, looks ridiculous, like you outgrew your suit a decade ago.
How about I toss out a FASHION BOMB and explode this to you: In addition to shirt sleeve, sweater sleeve, and jacket sleeve, it would be uber fashionable to wear a long sleeve undershirt as your first sleeve layer. Now, rather than three sleeve layers, you can have four sleeve layers and the sleeve of your jacket can now end at your elbow. Woah! Short sleeve suit jackets are gonna be in style! I'm trademarking this pronto. You read it here first.
