I have a hard time finding button down shirts that fit properly, I also don't like to spend a lot on them because, well, I don't. When I walked into a Thomas Pink store in DC this weekend I was shocked - the sale prices were amazing and their shirts fit incredibly well.
Even though the shirts are known basically as perfection,Thomas Pink is not a store I frequent because the shirts are around $180 full price but there was a huge selection of women's shirts for $49-$79. At the D.C store the men's shirts had been picked through although some did remain.
If you need this kind of shirt for work or have any kind of interview coming up I suggest you hurry over to your nearest store, or check out the website.
