Kyoto kimono rental advice for busty girls

Hi! My friends and I are going to be doing a kimono rental in Kyoto and I’m wondering if anyone had tips on what kind of bra to wear? Im 5ft 1, 127lbs 30 G so small band big cup and most sports bras aren’t ideal because either the band is way too big or the front isn’t covering everything. Also if anyone has suggestions for a size inclusive place? I wear a US size 4 but idk if thats considered plus size in Japan and if I should find a place for that. I’m sorry if this comes across super ignorant I just didn’t feel like I was getting a straightforward answer from searching online. Thank you for the help!
