Crop Long-Sleeve Top
First up: a crop long-sleeved pink top. It’s Wednesday, so let’s wear pink! Based on the product info, sizes of the top may run small so may want to choose a size up. Check their details to verify.

Square Pendant Necklace
Gretchen wears a necklace with a square pendant. Hers seems to have something inscribed on it, but a plain square pendant should carry the look across just the same. Get a sparkly one like this piece.

Brown Plaid Skirt
Gretchen’s plaid skirt is actually a pencil cut, but I was unable to find a pencil cut with a pattern, and we all know based on the dress code that you can’t have all solids for your outfit! This is a pretty cute alternative. On the photo, she pairs it with strapped high heeled shoes. For her earrings, wear studs.

Toaster Strudels
Here’s a fun extra prop for your getup. We all know Gretchen Wieners’ dad was the inventor of Toaster Strudels, so bringing this along to yoru costume party will be a fun inside joke among Mean Girls fans. Quick Trivia: there used to be a Mean Girls edition of these pastries, complete with pink icing and on the box the pink icing even wrote fetch on the tart haha! It’s too bad it is not longer available.
