Although this doesn't look very appealing, it is not unusual and will resolve. Were you to have been awake and aware during the procedure, you might have seen just before the closure that the bottom part of the skin was a gently curved but almost straight line, while the upper part was almost a semi-circle, with, therefore, a considerably longer length. Hence the puckering, pleating, or gathers. Were this cloth it would be permanent, but it is skin and the skin remodels as it heals. Very occasionally a scar revision could be needed after 6 months or so, but most of these do well and even out as they heal.
Thank you for your question, all the best.
