What to wear to job at Tjmaxx?

When I went in to take my final papers and was about to leave I was told to wear what Id normally wear to work. But I only have worked at a restaurant and hardware so it'd be a different outfit and I was dumb and didn't ask what their dress code was. So as I was leaving I just kinda sad what the other workers were wearing and it seem just like regular casual clothes. Ive never worked at a clothing store so if anyone has any tips I could use them.
