Image (Below) © Big Fat Betty | The gifted item I chose was the Alina Floral Textured Shift Dress in black (£18.00, sizes 16-24). I opted for my usual size (22) though I think I would have preferred to have sized up for a looser fit (as Becky from The Ramblings of Mrs BeBe did). The dress is very comfortable and just above knee length on me (I'm 5'7"); I chose to wear it with leggings but I think it's long enough that you could wear it with tights, too.
I have worn this dress practically non-stop since I received it; in fact, I'm wearing it now! Another thumbs up for boohooPLUS.
