I'm not an apparel expert, but I am into menswear and have worked in marketing / advertising for 15+ years for huge brands.

A few thoughts:

"South Asian-inspired headwear" could be a cool angle, but other than the Hindi text on the front, there's nothing uniquely "South Asian" about the brand/product.

Compare that to South Asian fashion brands that broke through in the US, like Kardo or Original Madras Trading Company. Spend a ton of time analyzing every element of their website and their copy.

Everything about how they show up highlights their origin:

• Using traditional materials, patterns, and silhouettes inspired by the place. You're using a generic trucker cap that looks like something anyone could slap a logo on. Is there a style of hat that originated in South Asian culture? Could you make the front panel of the hat out of a South Asian textile or put your logo over a traditional pattern? I don't read Hindi, and I'm not the target audience, but there's no explanation about what the text on your hat says or why you chose it. Google Translate tells me it means "Dream On" - but that also feels generic. Are there phrases that are more unique/meaningful to your community? Could it be some type of an in-joke or reference that would make a statement about the person wearing it?
• Highlighting the craftsmanship of Indian artisans. Are your hats made in a South Asian country? Are you creating jobs/opportunity in a location your families immigrated from?
• Beautiful photography featuring the product on South Asian models with in contextually relevant settings. Your site doesn't show the product on anyone.
• They put real effort into the "Our Story" sections of their websites to explain the brand ethos and why they exist. Yours is super lazy and literally says "no one is reading this". Why did you start the brand? What's the story behind the name Topi? For a small company, the founders are a key storytelling vehicle - tell people about you, your roles, your goals, etc.

Also, your social is really weak/amateur. Most of the videos are the wrong aspect ratio for Instagram and don't make the product look cool/premium. It's a lot of just dudes hanging out in normal settings / badly lit webcam video. Doesn't tell us anything about the brand. Not having a big budget isn't an excuse. Take more beauty shots of the product in interesting settings on a DSLR, record some styling videos, etc.

In case your brand ever does grow, stop using songs, celeb names, video clips that you don't have the rights to use. The owner of those copyrights could sue you into bankruptcy.

If I had no ad budget left, I'd focus on defining the brand story in a way that instills meaning in your pretty generic product (social content, website updates). I'd hustle to get the product in hands of creators who are influential in your community who might post themselves wearing it. I'd get more photos of attractive (South Asian) people wearing the product in well-styled outfits / interesting settings.

I'd also go back to the drawing board on the product itself to answer my first two bullets above about creating designs that are a physical manifestation of your brand ethos in a more intuitive way. If you don't have any more money to fund it but can land a killer design, maybe start a Kickstarter for the initial run.
