Peace be with you السلام عليك
You know it! Those maxi dresses are in full bloom and they all seem to be made of jersey fabric and they end up sticking to you, not very hijab friendly. Not to worry! I suggest getting a sheer maxi full length dress liner even though it may not match the top of your maxi dress it doesn't matter since your hijab and cardigan will be covering that area...right? right? But of course you already knew that. ;) This style of slip will only work on a dress style.
I would use the full length slips for the following maxis.
How about the jumper maxi? you can separate the two and get a top and a shorts slip that reaches the knees or one that reaches the ankles
