Waalaikum assalam sis! Semoga lancar bersalin nanti, 100kg tu memang banyak, tapi dengan harga RM550 mesti ada yang interested, especially parents yang pasal budget-conscious haha. Try post kat Facebook groups yang active macam Buy & Sell Selangor or KL second-hand groups, lagi ramai traffic kat sana compared to most forums, I notice a few of my mum friends selalu dapat respond cepat kat FB groups. Since baju mixed sizes, maybe highlight the range dalam title (adult to kids) so people tahu what they're getting, and upload a few clear photos of the condition je! Goodluck, makcik, hope someone snatch it up before your big day!
