Here are my picks. Hopefully they will become yours too. 

sequins: classyfied

im always a little skeptical of sequin. it can look cheap and its only really appropriate for holiday parties. the items below are pretty versatile and I can see them going beyond holiday parties. chambray shirt under the polka dot top for a casual look?

red top/ polkaot top/ long sleeve top/geo top 

skirt/ shorts

pink dress (madewell option)/green dress/ black dress/ black + white dress

cropped up on top
