Seems to me that a couple of good cotton shirts won't hurt, either. I am a fan of Brooks Brothers brand which I would buy only when they go on sale and with a gift card earned for CC points. The sales usually occur in July and December. The shirts are pricey when not on sale, but they last forever and they do make the wearer look like she means business. Machine washable and no ironing needed. I have had mine for five years at least and the only challenge is discoloration at the underarms, noticeable on the white ones, but not on the striped or blue ones. They come in several types of fit, and it does help to get to the store and let the salesperson size the buyer up and recommend the size and fit. Once that is done, they can be reordered without going to the store again.
