Love these colours on you! If you feel the shirt dress is too boxy, you can always belt it (even with a silk scarf if you want to keep the boho vibe going & would find leather to be too restricting in hot weather). I don't think the bracelet clashes, but some wooden jewellery may help to bookend your hair whilst still looking boho too.
The second dress is pretty too - lovely print and colours! I feel like the necklace gets a little lost in the pattern, though. Also, I don't know about you but, I don't like wearing necklaces in hot weather (unless over my clothes) because they tend to stick to sweat/ my skin. That might not be a problem for you, but I think earrings would look lovely with this dress as well
I also agree with the others about the lighter footwear - espadrilles in a cotton, canvas or rope fabric would be a good fit for a boho, summery vibe. Ankle wraps may be too restricting in hot weather too, but it's up to you if you go for flat canvas (like TOMS) or a wedge rope heel style. Bonus points if you also have a straw bag or floppy hat lying around - way to pull in the artistic & feminine side to your boho look whilst still being safe in the sun
