Clothing

Choose a professional outfit that has a classic look, how formal that may be depends on your industry. A conventional look is better for traditional industries such as medical and finance whereas creative industries like marketing and tech are open to a more casual style. We shouldn’t be able to tell what decade it is in the photo, so beware of dated trends.

I recommend avoiding bold, distracting patterns or colors, unless you can layer a jacket or sweater over it so not much of the pattern is showing. We don't want anything competing with your face. Clothing with tight grids or a small herringbone pattern can have a moiré pattern effect on camera (think of that anchorman's striped tie that seemed to be moving and grooving while reading the news), so stay away from grid-like patterns.  

I'm not a fan of stark white unless it’s under something, such as a suit jacket, cardigan, or sweater (doctors excluded). Our eyes are naturally drawn the lightest part of an image, we want that to be your face, not your shirt. V-necks accentuate the neckline and generally look best on women, just be cautious of the neckline - nothing too low. I also don't recommend turtlenecks as they tend to make you look like you have no neck at all, which is a NAGL (sounds like "bagel" and is "not a good look"). It's also preferred to avoid bare arms (i.e. tank tops or short sleeves). Again, we don't want that flesh competing with your face.
