(can you see the frame-shelf? when you push it, you'll fiond the fitting room!! it's like the Fashionable chamber of secret!)
I love the details!!! especially the basic tees and Neck accessories! The Makrame necklace and multi color embordiered neckpiece. and it's quite cheap if I may say! the huge neckpiece is only around IDR 500-600k. and the makrame is BELOW 200k!!! the tee with Tibetian words shaped-lace is BELOW 400k. and the prices of everything there are very reasonable. you can find a luxury lace dress too for around a million or two, but They really apply couture technique on rare fabric so it's explain the price!
I really recommend Happa for a place to buy daily wear and Dress for birthday party, wedding celebration, or even graduation! when you buy their piece, it feels like buying the fashionable comfortness.
