WHATEVER YOU DO, DO NOT WEAR A THONG!!!!!!!!
I worked for many years wearing all white (with a cap to boot - and I am talking months ago, not stone age with Florence). To put it politely, wear granny panties that have the elastic below your cheeks, and make it a neutral color of your skin (i.e. fair skin wear nude panties, dark skin wear dark tan panties). Don't let your husband tease you about the grannies, reserve the thongs for a more appropriate time! And, make sure your bra matches your underwear, as in whites, it is a faux pas to wear any other color than mentioned above. :redpinkhe
