When you go shopping, make sure all the roses are of the same color, and get the cheapest thong or g-string and bra preferably matching the color of roses or white or black. Also buy thick thread.
Step2
Cut the stems off the roses and on the other hand, put the thread through the needle.
Step3
You take the needle with the thread in it, pass it through the bottom of the rose (part where you cut the stem off) and sew it on to the cups of the bra or the front part of the thong or g-string.
