Headbands with soft and comfortable material are necessary for babies to protect their sensitive skin. I suggest you go for elastic headbands but if you want ones without big ribbons and flowers, I lurked online and stumbled upon these online shops. http://bowaholics.com/index.php?route=product/category&path=70&page=4 http://www.stylemelittle.com/product-category/accessories/interchangeable-headbands-base-options/ You can also check out Pinkbox's Eshop http://www.pinkbox.com.ph/infant. They sell elastic headbands with interchangeable plain colored laces. :)
Lazada has a good selection of baby items! They have vouchers, too, so you can buy them at a lowered price.
I get mine from @rainybowsph (IG) They have the bunny ears which are small knots and not the huge ones
