Allow me to first apologize profusely on behalf of Pomelo for sending you a substandard item.
We pride ourselves on taking extreme care to make sure all of our items are of the best quality when shipping out our packages and we have absolutely no idea how such a mistake slipped through the cracks. :( We hope that you accept our sincerest of apologies for any disappointment or inconvenience our mistake may have caused.
Next, we hope that we can make this up to you! If you're still a fan of the garment, I'll be more than happy to send you the item again - completely free of charge and, of course, free of defect this time around. If not, we're also happy to assist you in returning the item. Either way, we'll try our best to make sure that you end up completely satisfied with your time spent at Pomelo.
Please let me know which solution you would prefer and if you have any questions or concerns! Thank you so much for your patience and understanding. :)
