Not that good but average, if you want to look for your favourate t shirt or shirt it is quite hard to find, the products variations are limited to buy.
Website desktop interface is excellent with great flexibility and easy to search and buy products. And they don, t have any android version for this site, which shows that this site is not that quite popular.
Compare to flipkart, amazon and myntra. Swagshirts99 is not that much reliable for monthly clothes shopping because of their cheap products with limited number of variations. And the customer service is not that good.
According to My Experience
The biggest Drawback for this website is their delivery delayment. After buying your product, it sets an time limit that your product will reach within 4 days. But it crosses your time limit and comes after 7 days which made me sick. And their customer service irresponsible. So In my opinion if you want to buy t-shirt and you want that product to be delivered fast within 3 days then don, t buy from this website
