first off, get yourself a laced tank top. got it? ok and now get an old tee that you would like to make into a new tanktop got that? awesome. set aside the tee and get out your seamripperrrrrrrrr

and start ripping out all of the seams that connect the lace to the tank top. get it all off of there yeaaah get it. {i also ripped out the hem on my tee but uhhh you dont have to do that if you dont want to! i just did to add length} now keep that lace and the other part of the shirt because.....

you need to pin the old part of the tank [the white part] to your tee and cut it out so that it looks like so. and also dont forget to cut the back part of your tee! and i believe i had to sew up the sides a bit so it would fit to the lace so do that too if you gotta!

whew ok almost done! now all you have to do is pin the lace to the bottom and the top of your tee that you just cut out and get to sewing it together. aaaaaaaaaaaaaand now you are done! yay great job!!!
