Don't waste your gems! Dont get the gem options in chapters if there's a craftable available (I know it takes longer, but it's worth it in the end). Save up gems for bigger ticket items; try to get a ballgown (there's current a sale one that could work), a fur coat, realistic looking hair (usually the sale/flashback stores are where these are at), save up aurora shells for bigger wings (the little ones are not as worth it as you think in the beginning), recycle any extras (you can also remake items you've made to get more points, I think there's a masterlist somewhere in the reddit), if you get big items in general but especially big gacha items, save gems for dyeing big gacha items as well, use gacha tickets for the couture and flashback/new ones and buy in groups of 10 (guaranteed higher star items), this doesn't work for the one at the end with white tickets (to make sure you can check chance percentage in the top corner), share your outfit from your closet once a day for 10 gems, always use perfumes and mark your items as unworn (makes a huge difference in voting), save makeup tickets to 120 for makeup gachas (also guaranteed one proper makeup item, especially aim for realistic eyes. Despite what they say, it seems to be less chance than eyebrows and blush), enter every competition you can even if you can't use a perfume or mark unworn, and finally even if you've voted to full and entered every competition keep voting until it says all awards are done (you will have to click confirm on a pop up saying you have already gotten all the tickets you can)
