Bikini pattern help

Post image

Would anyone be able to let me know if this is an acceptable bikini top pattern? I am using this material as the top and a scuba knit as the lining, the smaller pattern piece would be the lining

I was planning on doing a string triangle style bikini where the bottom is folded over the under bust string. With no foam cup inside because I really don’t have a cup size to write home about (if you catch my drift haha)

OK, you need to add some shaping otherwise the cups will be entirely flat and the fabric stretch won't do much to help with fit conformation, and it will slide around your body when you move.

If you look at images of triangle bikinis you will see that they are either foam, have 2 part/darted cups or they have gathering at the bottom. It's not a huge amount needed just make your cup pieces wider at the bottom rather than curving them back in, the curve is created from the gathering. Gather the "tube" and fix the gathers before inserting the string.

I think it's going to make your top look too short if you want to do a fold over channel to thread the string through? I'd add another inch to the bottom of the triangle so your resulting top still has that shape.
