I think there must be a whole lot of people in the world who buy clothes without trying them on.
I have no other explanation for seeing people out in the world who look reasonably put together but wearing something completely unflattering. Not an unflattering item that happens to be the height of fashion - like, say, the tube-top like item where the ruching ends just below the bust making even the skinniest woman look pregnant - no I mean a perfectly serviceable top worn in such a way as to baffle me.
Case in point, the surplice wrap top.
I see many tops with a V neckline from a crossed wrap of fabric than ends just below the bust and is snug from the under-bust down. You'd think this would look good on anyone, but it has a fatal flaw. I see more tops like this worn with that under-bust seam creeping halfway up the bosom. Not only is this entirely unflattering, it also looks uncomfortable and sloppy; like the wearer doesn't own a mirror.
My fashion pet peeve of the day. That is all.
