If they’re on the tightest setting.
I bought this swimsuit around 5 years ago, and I love it to pieces, but when I tried it on recently, I remembered how much the straps hurt me.
I would normally have the straps on their tightest setting to support my bust, but being so thin they would dig into my shoulders. So I decided, instead of grumbling about it every year, it was time to get the sewing kit out.
If you do decide to take a stab at my tutorial below and have any questions, let me know and I can do my best to answer them.
