The Sims2fanbg boho dress has an easy fix. You can either deselect the feminine fashion choice in the game every time you want to apply the dress in CAS OR you can permanently fix it with
Sims 4 Studio. You will need a membership to download Sims 4 Studio but, it is free. Once you have installed the program open MY CC. Choose the file for the dress from the list on the right and the dress will appear in the middle of the screen. On the right scroll down to Fashion choice and tick the box next to Feminine and then Apply to All Swatches. At the bottom of the screen choose the green Save button and then say okay and you are done. You can also change what categories the dress will appear in if you like.
This dress is the exact same style as the ruffle dress:
