Umbrella from FUN shop

I won an Umbrella from FUN shop but when I double clicked it it disappeared and I don't know how to equip it. Can someone guide me on the right track? Thanks. Sorry if this seems nooby lol.

After you use an cosmetic ticket (accessories, hairstyles, etc.), you can go into the Salon to equip and adjust them. The Salon is located in the Shopping Plaza, up the stairs that are to the right of the Casino entrance. You can also equip them from the Fashion menu, but you cannot adjust them in any way from there.

...Actually, you don't even need to go to the Salon just to equip something--the fashion menu is under the second bottom menu icon from the left.
