heetlijk zacht materiaal en goede pasvorm

Few years ago, I bought 2 pairs of leggings from Relax, they were good! This year, on 14 August I bought 3 pairs of leggings from Relax. 2 out 3 leggings are great disappointment!!! The only pair which is comfortable is the Almond tree from Van Gogh. One pair is too low on the waist and the worst nightmare pair is this pair Wild! Today is the first time I wear it. It was ok when I put it on but on my walk to the gym, I was pulling my legging constantly. It became so loose at the elastic waistband. During the zumba lesson, I had to pull my legging a number of times because the waistband of the legging was not on my waist.
Once I was home I compared the 3 pairs of leggings I bought. They were all size M and this pair Wild, the waistband is bigger than the other 2 pairs. It is strange that this pair Wild does not had the Relax printed label.
Is this pair Wild legging from Relax itself or is it from Temu or Ali Express? I enclosed this hoots for comparisons. You see the difference in size although they are all size M. During 1 wearing, it has stretched so much in the waistband, how would it be if I wear it regularly? Please see photos…

Mooie, zachte legging, maat valt goed. Had hem alleen graag iets langer gewild.
