Super Smash Bros. Ultimate : Alternate Costumes

Alternate Costumes (also known as Alts, Color Changes or Palette Swaps) are selectable color palettes for playable characters featured in the Super Smash Bros. franchise since the first game. This feature was added to distinguish players from opponents who chose the same character. Alternate Costumes can simply be accessories (in the case of fighters such as Jigglypuff and Pichu), color swaps (Peach and Marth), true alt costumes (Mario and Bayonetta) or full on characters (Bowser Jr. has the Koopalings and Olimar has Alph). Since Princess Daisy makes a playable appearance in Super Smash Bros. Ultimate, she receives eight palette swaps as well. It isn't overtly clear if these alts reference anything but there is a lot of probable speculation.

Default
Daisy's default dress for Super Smash Bros. Ultimate was adjusted to look more sophisticated and intricate. The costume contain gold, flame-like designs in addition to silk extensions on the brink of the conclusion of her dress. She has matching flame patterns close to to her jewel in addition to frills at the the front of her gown that part down the legs, flame-like plans close her frills. The gown has a silk front on the point of her brooch. Daisy has moderate blossom motifs on her gloves.

Alt Three
Alt Three's primary color is blue but it has purple panniers, green pumps and white frills. The jewels on this alt are cyan.

Alt Four
Alt Four is arguably the most unique. The dress is red with grey panniers and black frills.

Alts potentially referencing Princess Daisy
#13 ~ Princess Peach

Since Melee, Peach has had an orange and yellow alt with orange hair as a reference to Princess Daisy. But since she is a fighter in Ultimate, this alt no longer exists. It has now been replaced with a golden one. It's rather ambiguous whether or not this new alt is a reference to Daisy since it is golden with white frills as opposed to yellow with orange frills. But the yellowish motifs in the dress makes it somewhat similar.
