I feel like I can pull myself together fairly nicely - but I have in my Mexico pile a few fancier t-shirts that I was planning to wear with skirts. Women will know what I am talking about - a short-sleeved shirt but with some embellishment on it - a tunic top or some ruffled edges - but they ARE just cotton, not silky shirts. Is this going to be an issue at the evening restaurants? I'm bringing a few dresses, as well. I'd class them as "mid-range shirts" - the type of tops you can either dress up or just wear with capri pants (which I see are also acceptable for women during the evening.) I'd be really embarrassed if I was asked to change, so please let me know if I'm good to go here.
