I have just finished amending a white buttoned shirt I bought that was too small on the bust. It now has flashes of pale green/white checked material up the sides, and a bias strip of same edging the collar. It looks pretty cute, and it fits a lot better. Trouble is, the original fabric is slightly see-through, and my only nude bra is a backless one that wouldn't be comfortable to wear with this. What should I dooooo? Any tips welcome.
