I’m going to say pair of jeans a few points why: 1) larger surface area - if you are looking at your outfit, your legs are going to cover 40-50 percent of your overall figure. Not only will the jeans look good but a well fitted jeans may showcase your legs or other assets that you many want to accentuate. 2) costs per wear - if you are wearing the jeans you want to get the most bang for your buck. A dark washed jeans could be worn in always a casual setting, but pushing it, in SOME formal attire. Given the person’s line of work, jeans may not always be appropriate, but a darker washed is more casual and formal. BONUS- if it’s super dark you won’t have to worry about color fading or getting to light after multiple washes 3) comfort/confident - jeans can be comfortable if you get the right size and after broken in can fit like a glove. A good pair of jeans will serve you a good period of time, but the important thing most people forget is how they FEEL when they but the cloths on. Does it give them the confidence they need to slay the day? Will You buy the jeans on and say, “yea, I look good”
