Another choice instead of nubra is hollywood fashion tape, it's kind of like a sticker you paste over your nipple but of course it's gentle to the skin around there. Can find at guardian or blogshops, i think they are selling at about $12+ per box. No creases also, so it won't show under your gown. It's one-time use, so after using for 1 time, you throw the sticker away. There are multiple pieces in a box of course. It's a more comfortable alternative as compared to nubra, I feel, because nubra you need to wear it for the whole day and it can get sticky. Of course the bad thing about fashion tape is that it does not give you that extra 'push' for your boobs to look bigger, because it's just a tape. Nubra would be better if you are small chested to give more volume.
