Post updated today. Previously I speculated based on a detail from the meme photo that our spudly heroine was wearing a gunny sack dress or draped in burlap potato sacks. After hitting "post" late last night I noticed that the higher-resolution pic from the San Diego archives showed a confirming clear image of burlap-weave fabric between and under the potatoes:
