Well, it appears Lorraine has been listening, and today she donned a dress from George at Asda.
A total bargain
And, in even better news, it'll set you back less than £20.
"Created in a button-down shirt style with a collared neckline for a little retro style, this pale green dress is a stylish way to welcome in the warmer weather!" said the blurb.
The sage green ditsy floral midi shirt dress costs £18 and is currently only available online in a very limited range of sizes.
The Lorraine effect, it seems, is in full swing!
Although it's worth a look in the George section of Asda next time you do your essential food shop.
"The short rolled sleeve adds a vintage vibe, and the self-tie waist belt adds some structure at the waist," the website added.
"Where's this dress from," asked one fan, adding the love heart eye emojis.
Saw it in Asda this morning. Such a nice dress!
