chief uniforms or do you mean chef uniforms.......if it's chef.try
www.uniformcity.com prices are good.
over in columbus there is a thrift store on the east side off livingston, they did/or still have very nice clothing, senior moment, I think it called thrift america. also the salvation army store on 161 near Morse.
Its hard to find plus size sequin clothes but I have seen some down here.its mostly those size 5 or less chicks.
The best time is the larger stores after the holidays.....I got a sequined sress that was over $100, for 11$, I will look for you.
There a thrift store in P'cola I'll check for you when I get moved back there, they used to get in lots of formal wear, and most not over $25, they used to have color of the tag day sales, and if that hits you get 50% off.
email me privately the sizes you need.
