"I brought my wedding dress to Diana for some last-minute alterations—just a hem and a little taken in at the waist—and I couldn’t be happier with how it turned out. The fit was perfect! The experience was easy and quick. Highly recommend if you’re looking for thoughtful, high-quality alterations!"

“I had the absolute pleasure of working with Thread Theory for the tailoring of my pink blazer dress, and I couldn’t be more thrilled with the results. This incredible mother-daughter duo brings not only skill and professionalism to their craft, but also warmth and kindness that make the entire experience feel personal and seamless.

Their attention to detail is impeccable—the fit of my blazer dress was tailored to perfection, hugging in all the right places while still feeling comfortable and elegant. They truly listened to my vision and brought it to life with such care and precision.

Thread Theory is a new gem in the world of tailoring in Mountain View. If you're looking for expert craftsmanship with a personal touch, look no further. I can’t recommend them enough!”

Brought my boyfriend here last minute because we discovered his dress pants for a wedding the following weekend were wayyyyy too tight around waist and thighs. We weren’t sure if they could be saved (he could barely button them) but thankfully we found thread theory and Diana worked some magic (before and after pics attached)

She managed to let the pants out just enough for a comfortable fit without compromising the look. The turnaround was quick, and the quality was top notch.

Highly recommend this place if you need expert tailoring on a tight timeline.

Bonus: it's a lovely mother-daughter duo running the shop!

Really great experience fitting my silk qipao which was too small. Super kind service. Fast turnaround.

The best thing about finding a tailor you connect with is that it’s like getting a new family member. The team at Thread Theory cares about your garment, how you look in it, how you feel in it, and how it performs for you while you’re wearing it. The attention to detail in their work highlights their 30 year career in professional tailoring. Their work is meticulous and high quality. They want to make sure you’re satisfied. My consultation with them was thorough and thoughtful. Diana took the time to deliver the highest quality alteration of my garments. I encourage you to take all of your alterations and custom needs to this team. They are such wonderfully warm and friendly people who will give you the very best service.

Thread Theory is incredible! I brought in 2 dresses and a backpack with a broken strap—Diana was super friendly and prompt in helping me, and pinned the dresses exactly how I wanted them. Diana was kind and clear during the check out process, and prices were very reasonable.

Less than a week later, Diana texted that the items were ready. When I went to pick up, Diana and her daughter Christina were both so friendly! They let me try on the dresses to confirm the fit—both were tailored to absolute perfection. Diana fixed the backpack perfectly as well, and she had reinforced the other strap just in case, free of charge!

If I could give 6 stars, I would! I am so excited to have a go-to tailor in Mountain View and I would recommend to anyone!

Absolutely incredible tailor! This is a gem of a local business run by a talented mother-daughter duo with years of experience. They fixed zippers on my handbag, ski pants, and jackets, and also repaired a delicate blouse — all done quickly, flawlessly, and with real care. The quality of their work is outstanding, and they’re both so warm and friendly. It’s rare to find craftsmanship and service like this anymore. Highly recommend supporting this fantastic small business!
