Lengha customization

Hi, all, was fishing for ideas to modify a silk blouse (worn with a silk lengha) very similar to the pic below. I was wondering what people had in mind to modify the sleeves - to make them longer I. E should I buy lace or mesh style material or should I somehow get a tailor to convert it to a long Kurta jacket etc.

Any ideas would help keeping on line with a more modest theme due to the wedding I’ll be attending.

Thanks :slight_smile:
