For this project I used a 'simple' sewing pattern (still felt so complicated as a beginner) from this Dutch website: https://www.stoffen.net/naaipatroon-zomerjurk

Pretty happy with the result, even though it does not fit as expected. It'll still be used as beachwear on my next holiday. 
Eager to get more familiair with sewing patterns, and hopefully make a few less mistakes next time. :)
