This place was jam packed today. If you wanted to try on a costume, they would radio to the back, have it pulled and you can go back to the dressing rooms. Unfortunately, the quality of the costumes in general these days is incredibly cheap - super thin flimsy materials with inadequate stitching. And the prices for what you get are high. You really are almost better off making your own.
In general, good selection of party supplies and lots of different themes. A bit pricey compared to Target and Walmart, or for that matter, the dollar store. Good place for party favors and balloons.
