MCK Clothing Store is a retail and custom-tailoring shop in College Area, San Diego, operating out of Suite 106 at 4644 El Cajon Boulevard near the intersection with Menlo Avenue in the 92115 ZIP. The store combines a ready-to-wear clothing floor with an on-site tailoring operation, producing tailored suits, traditional Vietnamese ao dai, and uniforms alongside its rack inventory. That dual model — off-the-rack browsing plus measurement and construction — positions MCK as one of the few independent shops on El Cajon Boulevard where a customer can walk in for a casual purchase and leave with a fitting scheduled for a made-to-measure garment. MCK's tailoring side shares the custom-garment corridor with NRE Prints/Insta Print SD, where screen printing and heat-transfer work complement MCK's cut-and-sew operation for clients producing branded uniforms or event apparel. The ao dai program serves San Diego's Vietnamese community for Tet celebrations, weddings, and cultural events, with fabric selection and fitting consultations handled in-person at the El Cajon Boulevard storefront. The alteration and repair service covers hemming, tapering, and structural adjustments on both in-store purchases and outside garments, extending the shop's reach beyond its own inventory. Personal-care stops including Happy Spa sit within the same commercial stretch, rounding out the self-care and grooming options along this segment of El Cajon Blvd. The store sits roughly two miles southwest of SDSU, accessible via El Cajon Boulevard's direct east-west run through the neighborhood. Ready-to-wear stock covers women's casual and semi-formal pieces alongside the men's suit inventory, and the shop maintains seven-day-a-week hours across a schedule that covers the corridor's full foot-traffic window.
