Dress for Success is a 4-player and duel minigame appearing in Mario Party DS. It is a card minigame involving memory, where players have to keep track of the shuffling cards and remember where the right one is.
There are four rounds in this minigame, in which each round a card depicting one of the four characters will be shown on the upper screen. This is followed up with four different cards shown on the lower screen for a brief second, which will then be flipped and shuffled around.
Remember where the correct card is and keep track of its movement, and tap whichever card you think it is with the stylus. Beware that in each round, in the pack there will be a card that is very similar to the actual character model, but with an incorrect design alteration (like Luigi having three buttons as shown in the image). Such cards are there to fool the player.
