We have seen this in all spring collections and I must say they are awesome. But I haven't been lucky enough to find one I could usually buy so I decided to do my own version, and it's pretty easy.
- Thread and a needle
- measuring tape
- elastic lace band
First you'll meassure your chest with the measuring tape.
Then you will cut the lace band with the same measure as your chest measure.
You are gonna sew the two edges...
AND IT'S DONE!
