If you keep your overall style simple, you're guaranteed to give her the right impression and avoid a fashion faux pas, which can be a big turnoff for many women. The trick here isn't to really change your entire style for that one single date, but rather to ensure that your pieces blend well together. Simplicity should be a guideline across the board, whether it's for shoes , sweaters or pants. For example, when choosing your pants for the evening, don't go for an extra tight or extra baggy pair. Instead opt for fitted pants, which is a compromise of the two styles.
Simplicity is about avoiding extremes.
It's a good idea to be a little more conservative on the first date and then, once you start getting to know the person a little more, you can start showing off the more risqu side of your wardrobe. The same concept applies when selecting your sweater or shirt. Stay away from something too tight or revealing. This applies to men with good bodies as well as those who are less fit. Let her wonder what you look like under your shirt or sweater.
