Cap sleeves. WHO do cap sleeves flatter?! I have broad shoulders to begin with, so when I wear cap sleeves my shoulders look broader and my upper arms fuller. It's a lose-lose for me.
Gold stitching on dark denim. This is more of a matter of taste, however I feel like gold stitching makes a jean a whole lot more casual. Obvious stitching also makes me feel like I have to coordinate it with my outfit, and I ain't got time for that. I do have one pair (which is now 60% off!!!) that almost violates my preference, but I deem them a medium wash, so it's okay ;)
Pompoms. I feel like a craft store, and yeah that's enough to keep me from wearing it.
Popovers, half-button-downs, whatever you wanna call them. While yes I own a select few of these, namely my absolute favorite flannel tunics, for the most part I don't even bother trying them on. They don't seem to tuck as nicely, and I typically require assistance getting one off over my head. Since I'm not 4 years old anymore, I figure I should nix things that limit my ability to dress myself...
Button downs without collars. Again, I own a couple exceptions, but for the most part blouses with buttons and no collars are a pass. I layer and I love collared shirts, and typically blouses like this just don't play well with others.
Hot pink. I'm rather pink, hot pink is very pink, so together we just look pink. It's also kinda girly and I'm not usually drawn to girly things.
Polyester shirts. Guys, I have armpits and they like to breathe. Polyester doesn't like to let that happen.
So now that you probably think I'm crazy for all my weird shopping hang-ups... Anything you automatically pass on while shopping?
