How to Add a Side Stripe to a Rashguard

This post contains affiliate links that help support my blog.


As part of the Raspberry Creek Fabrics Blog Tour, I shared the Boo! Designs Swimmers Rash Guard with a side stripe running along the sleeve and side. I thought I’d write a separate post with instructions on how I did it!


To make a 2″ stripe, do the following (note you can make a wider stripe – you’ll just need to adjust the math a little).


  1. Remove 1″ from the side of both the back and front bodices.
  2. Remove 1″ from both sides of the sleeve.
  3. Cut a strip of fabric 2 1/2″ wide and a little longer than the total length of the 1″ strips you removed.
  4. Sew sleeves to bodices.
  5. Beginning at one hem, attach long strip all the way from shirt hem to sleeve hem. Repeat for other side.
  6. Sew your shirt together – you may want to make a notch where your underarm is on the long strip, just to help keep things aligned properly.
  7. Trim off any excess strip and hem.

Happy sewing!
